What Does the Yield Mean in Chemistry?

What Does the Yield Mean in Chemistry?You've probably heard of a formula called 'yield', which is one of the most important things to know when taking a Chemistry course. In this article I will explain what yields are and how you can use them to your advantage.Yield is a concept in the Fundamental Science Unit (FSU) class that chemistry students take before entering the second year. The main purpose of a 'yield' is to understand 'landscape' in chemistry, also known as the 'chemistry landscape'. This includes structural and chemical properties of things, as well as changes in these properties as you go about your daily activities.The difference between the chemistry landscape and the landscape of a house is huge. The biggest difference is that the landscape of the house has been created by the owner and changed over time. These properties change as you do your day-to-day activities, with a massive change of environment in store for you. It's basically a guide to help you remember all the little things that happen every day, including the ingredients that you need to make some things.To get a good understanding of 'yield', you need to find a way to visualise what you're going to be making and why. You need to have an idea of how many materials you're going to need in order to make something, how much it's going to cost, how long it will take and how much you'll spend on materials.Next, you need to consider the physical property of the substance that you're trying to make. It can be in any state (solid, liquid or gas) but it should hold its shape. It should be easily worked with and not too messy.In order to use 'yield' in Chemistry, you need to work out the actual yield, either through experimentation or the information given to you by your teacher. However, this can often be difficult to do, especially if you're really new to Chemistry. So don't worry, I've got some great advice for you below.You can use 'yield' to work out how many moles of H20 you will need to convert one mole of hydrogen into another, or how many of each element you will need to create a product. You can also use it to work out how many times you need to use hydrogen peroxide to get a certain volume of the substance into solution. And you can use it to work out how much time you need to use water to make something boil - it doesn't matter how many moles you need to use.Finally, when looking for ways to use 'yield' in Chemistry, you should also be looking at what is the minimum amount of a compound required to create a product. For example, you could use 'yield' to find out how many times you need to use 2 grams of lithium carbonate to make a new battery. Or you could use it to find out how many hydrogen peroxide milligrams you will need to use to make a product.

Irvine AP Tutor 5 Ways to Improve AP Exam Score

Irvine AP Tutor 5 Ways to Improve AP Exam Score AP exams: 5 Ways to Improve Your AP Exam Score From an Irvine AP Tutor Its that time of year again when students begin to start thinking about their advanced placement exams. Most students are taking AP classes by the time theyre in their junior year but some are starting to take courses sophomore year. AP courses require a large amount of homework and many important tests throughout the academic year but nothing compared to the final exam in May. Most students become overwhelmed by that point in the year because theyre also thinking about taking the SAT or ACT and their minds are exhausted from doing so many educational tasks that have occurred earlier in the year. The best way for students to overcome stress and do well in the spring is to start early and plan ahead our private Irvine AP tutoring will help you score high on your AP exam. 1.     Identify areas to improve If students try to study every single piece of information within their textbook, theyll become overwhelmed very quickly. Instead, students are encouraged to look at their personal strengths and weaknesses in their AP courses and figure out what they need to hone in on before they start their study sessions really. Topics they already feel 100% on can be reviewed but wont require quite as much effort. One of the best ways to identify strengths and weaknesses is to work with a tutor one-on-one or make an appointment with the classroom teacher at lunch. Its often easier for another person to identify patterns and then give good advice to the student. 2.   Create an outline before studying Another great thing for students to do is create an outline before they begin their study sessions. A student can identify different topics that may appear on the exam, look at different time periods they need to study or make a list of difficult concepts. This way they can tackle their study in smaller chunks and improve self-esteem by knowing they have accomplished and entire topic. Outlines also help keep students organized and help them manage their time (READ: AP Test Without the Class?). 3.   Take a practice test Its really important for students to take a practice test before they get too far into their study session because it will help them understand the format they will need to be familiar with on the big day. Each course will have slightly different formatting, but standardized testing is uniform across all topics in some respects. Students also need to get used to the short amount of time they will have to answer questions or write an essay. If a student scores lower than a three they know they have more work to do. The sooner they find this out, the more likely they will be to improve. 4.   Refine writing skills Nearly every AP course requires excellent writing skills. Students either need to complete a free response question or write an essay of some sort. In particular, many students need to work on making their writing more concise and cutting out words that are unnecessary. This will get their point across more easily and also help cut down the amount of time it takes to complete the response. As an bonus, refining writing skills will also help students with their SAT and ACT prep. 5.   Develop a test prep strategy After students have been studying for a while, they should develop a personal test prep strategy. How many points do they wish to improve? Which colleges are they applying to (this could make a difference as to what score is acceptable)? Do they need to work on speed when it comes to reading or writing? Do they need to work on concentration? These questions are difficult for a student to answer on their own and so its always good to have the help of a tutor, study group, or classroom teacher to develop a strategy that works for the student’s individual learning needs.

Ellson Education

Ellson Education Ellson Education A MESSAGE FROM US: Hi! Im John, Foreign Business Training Director with Ellson Education. Ellson was started by former educators who werent content with the Chinese public-school system and the mentalities encouraged in those classrooms. In China, its not unusual to have 50-60 kids in a classroom to one teacher, and theyresimply given information to memorize and regurgitate for tests. The kids usually have an incredibly taxing schedule, starting their days around 6 AM, continuing school till 5 PM, and then going to extracurricular activities until 8. Then they have to complete the homework theyve been assigned throughout the day. Theres usually little time for children to pursue things for their own enjoyment, or even to spend time with friends. This is why at Ellson our emphasis is kids learning askids!Our classrooms and curriculums heavily emphasize Project Based Learning (PBL), so lessons are always supplemented with songs, games, performances, and crafts. We work hard so thatour students look forward to their classes at Ellsonas a way of learning interdisciplinary English through having fun! We also emphasize critical thinking by using these activities to encourage kids to question and learn through their natural curiosity. This is the best way of ensuring that they not only gain knowledge, but retain it! Having lived and taught in China with Ellson, I understand what an enormous step this is for many educators.It can be intimidating to move across the world and live in a new place, especially if you havent learned the language yet. Thats why Im here, to be your advocateand liaison and help you make the transition to China.

Free Help in English Speaking

Free Help in English SpeakingIf you are wondering why there is not much help available for free English learning to speak on the Internet, then consider this. There are very few places where one can get really good free help in the English language. It is rare to see any online webmasters who offer English learning speakers assistance.They will not bother to give out information on how to pronounce the English language.

Even if they could learn a few words at the beginning, most of the time they would have to find a way to learn English speaking without paying anything.One of the major problems with this is that reading comprehension and speaking skills will never improve when people pay to get the help. People who could get help for free usually do not have enough motivation to continue on learning. This is why the on line webmasters of the Internet are making use of paid advertisements instead of giving help to their readers.The problem with these ads is that the readers do not even get to see the speaker's name or the webmaster's face in order to be able to realize that they are reading a well written advertisement. These ads make the reader believe that the content of the ad was written by the speaker himself or herself. This is the reason why online reading comprehension and speaking skills were never taught to the people on the Internet before the present times.However, with the advent of the Internet, online reading comprehension and speaking skills were taught to all the people on the Internet. That is why one has to visit the Internet in order to get free help in English speaking. Just imagine how different life would be if you could just get help in reading the English language from the beginning.

There, you will find informational articles and printable worksheets to challenge your skills.A sin gle article lists the most important geometry definitions:line segment: a portion of a line that is between defined pointsray: the segment of a line from a set point, and any points along that lineangles: acute angles, right angles and obtuse angles, and what defines themselvesthey also feature straight angles, reflex angles and complementary/supplementary anglesEuclidean geometry and postulatesIntersecting lines, line midpoint and bisectorsIn one fell swoop, ThoughtCo covers basic geometry; the rest of their pages on the subject cover more advanced concepts with accompanying worksheets you can print and work on.With ThoughtCo, you can regale yourself with all of the basic geometry you need: equations, examples and worksheets. Our next website provides video instruction… Of you're left scratching your head over analytic geometry or even word problems, there is help to be found online Image by Gerd Altmann from PixabayKhan AcademyWith Khan, the difference between the American education system and our is much more pronounced; all of their material is organised according to the US education system.Khan affords you the option of searching for learning materials by ‘grade’ which roughly corresponds to our ‘year’ system. For instance, a British Year 10 student is roughly equivalent to an American 9th -grade student... but there are no firm, parallel lines between the levels, so you may have to hunt around a bit for exactly what you are looking for.Another point to remember is that American math students generally do not encounter geometry until they are in secondary school so, if you select ‘geometry’ from the site’s homepage, you will be directed to ‘high school geometry’ - which may well be where you need to go.Keep these points in mind as you search for geometry instruction on Khan!Now that you’ve arrived at the ‘high school math’ page, you may start your instruction by going over the bases of geometry: angles and polygons, and calculating the areas of such.Don’t forget to partake of their full overview of the Pythagorean theorem!You may also choose to move on to the topic you need the most help with: congruence, similar triangles, trigonometric ratios…Each segment is clearly marked; you can search for the topic that particularly interests you (or bedevils you!), watch the videos on that subject and then take an exam.If you’d rather not create an account and launch yourself headlong into video instruction, you may read the review articles listed at the bottom of the maths/geometry page.Both of these American sites provide fantastic resources to master the fundamentals of geometric figures, now let’s get a bit more international.Massive Open Online CoursesIf you are preparing to sit your GCSEs or A-L evels, you will probably need more advanced materials to study from/with.The new wave in education, these MOOCs, may just be the thing that will get you ready to sit your school-leaving or university entrance exams.As their name implies, they are conducted strictly online and they are open to anyone who has an interest. Some courses cost a small fee while others are completely free but for enrolment into the website or programme.Many top-name schools often host such courses but combing those schools’ websites to find them might bring you more frustration and aggravation than it’s worth. The solution for that is… you guessed it: another website (or three)!Coursera is one of the top names in MOOCs. They offer everything from free courses in AI and algorithms to a full degree course to earn an MBA. Their courses usually originate from top-named US schools.Their curriculum is unfortunately not tailored to anyone needing an in-depth understanding of geometric constructions; theirs is more of a hit-and-miss proposition.To wit, we searched their database for a geometry course and, while they had one listed, it was not currently active. Still, Coursera has plenty to offer; they are well worth bookmarking for later exploration.FutureLearn works in much the same way as Coursera and also originates in the US. They are less inclined to offer courses at no cost.If you are feeling adventurous, you may try MOOC List.They compile and list MOOCs from any school, anywhere in the world. No need to worry; they let you know where the course originates from and which language it is taught in.Remember, in the introduction to this article, that we said everything ever put into cyberspace is still there?That also holds true for MOOC-list; some of their course listings show a start date of 2016!  But then, some show an imminent start date too. Maybe they just haven’t gotten around to culling all of the outdated classes…Have you considered finding a geometry tutor who will hel p you master Pythagorean triples and similar geometry problems? Before you err into the land of the polyhedra, take a moment to master basic geometric formulae Image by Gerd Altmann from PixabaySites to Help you Learn GeometryIt’s quite nice that our American friends put so much geometrical information into cyberspace for all to learn from but we Brits have a few pages of our own to turn to.Take, for instance, Teach It Primary.Their geometry resources page is targeted to Key Stage 2 students so that they can better understand shapes: comparing and classifying them, their properties and how they are constructed.If you feel the need to investigate a quadrilateral in depth, their exercises blending quadrilaterals and scissors are sure to be a hit. Conversely, if calculating the area of a circle or distinguishing the types of triangles stymies you, there, you would be well-served.From the table below, you can find a summary of the geometry help - some that we’ve listed in this article; their web addresses and what you can find there.List of Helpf ul Geometry Web PagesSite NameWeb AddressWhat You Will FindKhan Academywww.khanacademy.orgInstructional videos and worksheets organised by level (designed for US students!)Thought Co.www.thoughtco.comArticles, worksheets and geometric formulasCourserawww.coursera.orgOpen online learning courses pertaining to geometry or other geometry applicationsFutureLearnwww.futurelearn.comGeometry and geometry-related open courses (as available)MOOC Listwww.mooc-list.comAn assortment of MOOCs; a search will pull up all geometry-related coursesTeach It Primarywww.teachitprimary.co.ukGeneral math learning resources including a page for geometryTTS Groupwww.tts-group.co.ukShapes, puzzles and various geometry-related items for saleHomeschool Mathwww.homeschoolmath.netGeometry lessons and worksheets; links to further geometry learning sites (designed for US students!)Analyze Mathwww.analyzemath.comAbundant math resources including geometry formulae and worksheetsWhether it is the humble triangle or t he lofty-sounding parallelogram that is giving you fits; whether you want to deepen your trove of knowledge about geometric shapes in general or theorems in particular, you can turn to any of these pages for the information you need... without having to figure out the right question to ask your browser!Don’t stop now!

How to Survive the College Application Process Part One

How to Survive the College Application Process Part One Its August and youre about to dive into your senior year of high school. Its also time to jump into the college application process (if you havent already) which, at times, can be a little stressful. Over the next few months, youll write several essays, send many transcripts, and fill out seemingly endless piles of paperwork. Its a lot of workbut once youre done, the payoff is so sweet: admission into college and plenty of time to enjoy the remainder of your senior year of high school. Want to learn how to make it through as painlessly as possible? This first installment of a three-part series will explain how you can survive the college application process: 1. Start early When it comes to applying to colleges, the earlier you start, the better. Completing one college application by itself may take several hours. Many high school students apply to five to eight colleges, so applying to all the schools on your list is a significant time commitment. What you dont want to do is wait until the last minute to complete your applications. This will undoubtedly lead you to rush, and thats stressful. But besides the extra anxiety youll feel is the increased possibility of you forgetting to complete a part of an application (a common mistake). Take out your calendar now to set aside a schedule for working on your college applications, and stick to it. Set up a schedule that gives you enough time to complete your applications at least a week or two before theyre due to give you extra wiggle room to review and revise your applications before sending them in. 2. Educate yourself Its important to know the ins and outs of completing each application you plan on submitting. While many colleges rely on the Common App, each college has its own specific application process and requirements. It will save you time in the long run if you spend time now researching the application requirements of each college to which you plan on applying. 3. Stay organized Once youre familiar with colleges application processes, create a checklist that will help keep you on track. Write down the names of all of the colleges you plan on applying to. Then, beneath each colleges name, list its specific application requirements, such as an essay, a transcript, and letters of recommendation. As you go along filling out applications, you can easily cross the items you complete off your list. This can help ensure you dont forget any aspects of the applications you need to complete. Additionally, because it gives you a visual of the tasks you need to complete, keeping a list can help you better manage your time as the application process progresses (and gets busier!). 4. Dream big So youve started researching the application requirements of the various colleges to which you plan on applying. As you do this, you may notice that many colleges and universities publish the average standardized test scores and GPAs of accepted students. For some universitiesespecially Ivy League schoolsthese scores and GPAs are very competitive. But just because some colleges are tough to get into doesnt mean you shouldnt apply! Apply to a variety of schools, both those youre more confident about and those you may think are a stretchit doesnt hurt to apply to a couple of reach schools to further challenge and motivate yourself. After all, youll never know if you might be admitted into the school of your dreams if you never try applying! See Part Two of this seriesfor what to do next...

It’s thought to be forty thousand years old.From this Paleolithic figure found in a German cave â€" through the statues of Mesopotamia, the Hellenistic sculptures and Roman art, through the Romanesque and Gothic reliefs and architectural sculpture â€" to the nineteenth century, sculpture was dominated by a number of themes.Primary among these were religion, spirituality, and ritual. Some of the most famous images from the art world â€" the Great Sphinx of Ancient Egypt, the statues of deities from Greek and Roman sculpture, the carvings and reliefs from Romanesque and Gothic art, like Chartres Cathedral â€" are all essentially religious icons. They were merely commissioned by people with money (i.e. the Church) and created by artists.It wasn’t until the High Renaissance, really, that the connection between the art of sculpture and religion was broken. Whilst sculptors like Michelangelo, Donatello, and Leonardo da Vinci used relig ious imagery, from the fourteenth to the sixteenth century, sculpture became more concerned with anatomically accurate and naturalistic representations.And this shift changed the history of sculpture. Through Baroque and Rococo, through neoclassicism and up to the modernism, sculpture was about rendering form accurately with a representational eye.Whilst Auguste Rodin was the hugely influential sculpture artist that triggered the turn to modern sculpture, Constantin Brancusi was the figure that gave the art form the inspiration it needed to move away from the representational form.His abstract sculpture really paved the way for contemporary sculpture, by reminding people that painting and sculpture did not need to be representational at all.Learn more about the history of sculpture!The Most Famous SculptorsPeople are often interested in hearing about the most important, influential, and famous sculptors around. And honestly, there are a lot of them.However, the important thing to re member is that, as any art historian will tell you, for most of the history of art, we weren’t so focused on the names of painters, sculptors, and writers as we are now.The earliest known sculpture from the ancient world â€" from the classical period but also from the ancient civilizations preceding this â€" art was not considered so much of a personal, individualistic mode of expression. Rather, it was something more of a social enterprise, a dedicative activity.Consequently, some of the most famous sculptures we have â€" chessmen made of mammoth ivory, ancient art from Mesopotamia, the high relief found on old cathedrals â€" these are unattributed to any individual. The ‘famous sculptor’ is a category that is necessarily going to miss people out.Again, it wasn’t really until the Renaissance that sculpture, as for the rest of the visual arts, came to be considered through the lenses of individual names. Names like Benvenuto Cellini, Leonardo da Vinci, Michelangelo Buonarrot i, these came to be associated with some of the most beautiful pieces of art sculpture ever made.However, even these dudes didn’t work alone. In their respective sculpture workshop, they had many assistants, students, and observers. And so, even at this point, sculpture was always a collaborative task.Of course, the history of sculpture has remembered only these names â€" just as it has remembered the names of Gian Lorenzo Bernini, Antonio Canova, Pablo Picasso, Auguste Rodin, Henry Moore, Marcel Duchamp, and others.It was the vision of these people that was so influential. However, to limit the history of the art to famous names does a disservice to all the others who contributed to its progress.Read more about the famous names in the history of sculpture. The Statue of Liberty is one of the world's most recognisable public artworks.

(It’s never easy, is it?) Because, as we have alluded to above, sculpture is not just an art, simply, like a novel. Rather more like painting, sculpture has a whole host of different functions.Sculpture isn’t just Michelangelo’s David, or Rodin’s Thinker â€" each of them seeking to be art for art’s sake, a little piece of har mony and beauty.Sculpture, more realistically, is decorative. It idealises. It is religious and ritualistic. It is bought by power and serves political ends. It shows the world who has lots and lots of money.Sculpture represents an awful lot of different functions. And some of the most famous sculptures have little to do with art at all.And you’ll know some of the most famous sculptures immediately. The Statue of Liberty, say. Rio de Janeiro’s Christ the Redeemer. Mount Rushmore, the Great Sphinx of Giza, or the Trevi Fountain.These works, from the earliest to the most modern, are famous not because of the beauty of the art (maybe with the exception of the latter), but for the values, powers, and ideas associated to them. And so, the Statue of Liberty is known less for the intricacy of its design and more for the US idea of ‘liberty’ that it draws upon.These, really, are the sculptures that become famous: the huge works of public art. Next to these â€" which are so bound up with national, economic, and familial power â€" the others don’t really stand much of a chance.Which are people more likely to know? An innovative statue by Henry Moore or Rio’s famous sculpture? Constantin Brancusi’s game-changing work or a statue of Winston Churchill?Fame isn’t everything when it comes to sculpture.Learn more about famous sculptures here. Mount Rushmore is one of the most famous sculptures in the world.The Different Forms of Sculpture.As in any field, there is a lot of different terminology to learn about sculpture.How does a sculpture garden differ from a sculpture park? What is the difference between relief and sculpture in the round? What is kinetic sculpture, sound sculpture, and land art?And, crucially, how do we differentiate between the array of different art movements and styles throughout history?These are questions which, to answer properly, you need an in-depth knowledge of the form. Or a detailed glossary with clear explanations. This, by the way, you can find in our extended article on the different types of sculpture.But here, let us say, with the poet, T.S. Eliot, that the history of art is a continuous tension between tradition and individual talent. If a sculptor works in a completely idiosyncratic style, nobody is really going to understand what he or she is going for. If that sculptor builds on the work of past sculptors, however, audiences will have the knowledge and reference points to navigate the different ideas and styles that the sculptor is going for.So, different styles of sculpture, whilst they might seem miraculously new, are actually always built on previous movements and styles.Take Michelangelo. His work is thought of as the peak of Renaissance sculpture. Yet, he was building on the ideas and techniques of Donatello, Brunelleschi, and Nicola and Giovanni Pisano.The same with Rodin â€" another considered completely innovative. Yet, his work was a response to and development of the neoclassical and romantic styles of his day.This is the real birth of new sculptural styles. Not just a sheer ingenuity. The Trevi Fountain is Rome's centrepiece.Where to See Sculpture Collections.Finally, then, let’s talk about some of the best places to find the best sculpture. All over the world, there are museums housing exquisitely beautiful objects. Of course, however, some are a little better than others.Start with Rome and Florence. These are the homes of the Italian Renaissance â€" and the former also boasts being the seat of late antiquity. These Italian cities are like living museums.Then head to New York, where the Guggenheim, the Metropolitan Museum of Art, and the Museum of Modern Art will blow you away with the variety of their work.Then there’s Paris and London, the capitals of two countries whose colonial history has collected all the treasures of the world.For more amazing locations for sculpture, read our article!

Tangent Cosine Sine Tutors

Tangent Cosine Sine Tutors Trigonometry is the branch of Mathematics and it involves the study of the measure of triangles, their angles and their sides. Trigonometry is based on six important trigonometric functions known as sine, cosine, tangent, cosecant, secant and cotangent of a particular angle. Sine, cosine and tangent of an angle are considered the 3 most basic trigonometric functions and the measure of the remaining 3 trigonometric functions can be derived from them. With the help of these trigonometric functions, we can find the measure of the sides and the angles of any given triangle. Example 1: Express sec()/ cosec() in terms of tangent of the angle, tan(). Given expression: sec()/ cosec() Now, secant of an angle, sec() can also be written as 1/ cos(). == sec() = 1/cos(). Similarly, cosec of an angle, cosec() can also be written as 1/sin(). == cosec() = 1/sin() Therefore, sec()/ cosec() = (1/cos())/ (1/sin()) Taking the reciprocal, we get: sin()/ cos() Now we know that, sin()/ cos() = tan(). Therefore, sec()/ cosec() = tan() Example 2: Simplify the given trigonometric expression [tan() * cot()]/ [cosec()] Given expression: [tan() * cot()]/ [cosec()] Now we know that tan() = sin()/ cos() Also, cot() = 1/tan() and therefore it can also be written as cot() = cos()/ sin(). And, cosec() = 1/sin() Substituting this, we get: [tan() * cot()]/ [cosec()] = [tan() * 1/tan()]/ [1/sin()] Hence this gives: 1/ [1/sin()] = sin() (By taking the reciprocal) Therefore, [tan() * cot()]/ [cosec()] = sin().
