Percentage in Chemistry

Percentage in ChemistryA percentage in chemistry is a way of measuring a formula or substance in terms of its density, weight and volume. It is also a way of measurement to make any formula match the specific type of things in life that it is being used to deal with.In chemistry, this concept of a percentage is called the density or mass, or weight. In other words, in a measurement of volume, the value of percentage is measured by dividing a certain quantity of fluid into the mass of the substance in question. For example, you need to know how much sugar is in a single sugar cube in order to calculate the volume of the cube in ounces. The solution is to first find the density of sugar, then find the volume of sugar in ounces.The percentage of sugar is calculated in the same way, except that you will use the above volume to find the percentage of the cubic meter. The percentage of cubic meter is often called liter. Just like volume, the percentage of sugar cube is another unit in the same equation as sugar. Once you have found the volume of a sugar cube, you can also find the percentage of the volume.In making this calculation, you will look at the volume of the sugar cube and divide it by the cubic meter to find the percentage of the cubic meter. This percentage of the volume of a sugar cube is called the sugar content of the cube.This is a great experience for a child to learn to solve a problem like this, and is an essential part of learning the formula for any type of thing that has a volume and weight. This type of solving comes from how many different things there are in life.It helps children see that it is not just a number in the spreadsheet but it is a part of their own world. It helps them understand the level of abstraction needed to see it as such, and is just one more way of understanding that they are in charge of their own world.For any calculator to give you the correct answer, a mathematical formula called an area calculation needs to be used. To use the formula in chemistry, the percentage of sugar cube is placed in the formula and multiplied by the cube's density, then the percentage of sugar in the cube is multiplied by the sugar content of the cube, and finally, a conversion factor is used to convert the converted sugar to the sugar cube's volume. From the percentage of sugar cube, the ratio of sugar to sugar cube is entered into the calculator, and the result is calculated.

Am I Ready to Apply to Medical School

Am I Ready to Apply to Medical School Your prerequisites are complete, youve taken the MCAT, and youve lined up your recommendationsall thats left to do is begin your actual application process. But before you start the tasks involved with that process, you may be wondering if this particular application cycle is right for you. Could you assemble a stronger application by spending a year or two off doing research, community service, or taking extra classes? Or is your application strong enough for matriculation as is? This checklist can help you answer the burning question, Am I ready to apply to medical school? Decide if your MCAT score, science GPA, and overall GPA are all competitive enough for your prospective schools Before you fill out your primary application, you need to be honest with yourself about your statistical chances of admission to the medical school(s) to which youre applying. If your MCAT score is below the average of admitted students there, you might want to forego the current application cycle, seek MCAT tutoring, and put your energy into retaking the test. Similarly, if your science GPA or overall GPA is low, you might want to skip this cycle to boost your GPAs and prove that you can handle the academic rigor of medical school by taking some extra classes or by enrolling in a special masters program. [RELATED: How to Write a Resume for Med School] Examine any other responsibilities you have that might complicate your matriculation Have you signed a job contract that extends for a certain period of time that would make it difficult for you to get to admissions interviews, or that would interfere with your enrollment next fall? Do you have any special family commitments that you might temporarily want to devote more time to before you enter medical school? Surveying your own goals and responsibilities before you decide to apply to medical schoolon both a professional and personal levelcan help you determine what application year will be best for you. Ensure you have the necessary funds for both medical school and your application cycle Youve probably heard that medical school itself is extremely expensive, and you may have already decided how you intend to pay for it. But even before you must pay for medical school, you must pay for your application cyclethis includes registering for the MCAT, sending in your primary applications, and submitting your secondary applications. If you are fortunate enough to be offered a medical school interview, you may have to account for travel expenses as well. While there is financial assistance available for medical school applicants who meet certain criteria, it is likely that you will end up paying at least some of the bill for the application cycle yourself. Before you decide to apply this cycle, make sure you have decided how you will financially handle both your application cycle and medical school itself. Ensure you are mentally ready for the admissions process and the medical school journey Many students may find that by their senior year of college, they do not feel fully prepared to immediately embark upon another several years of study. Whether you are just about to graduate from college or have been otherwise preoccupied with another academic or professional endeavor, it is essential to assess your mindset and overall readiness to navigate the medical school application process (as well as to become a medical student!). If you find that getting back into the classroom seems too daunting or unrewarding at this time, it may be best to choose a later application cycle for yourself. Applying to medical school will always be an option, so relax and choose the application year that best ensures that you will matriculate as a strong and stable medical student.

English lessons usually emphasize spelling rules as a facet of basic English, rather than delving deeper into each word and how it acquired its meaning, and how its spelling and meaning have changed through time. But don't forget the many exceptions in the English language.The English vocabulary is made up of words from several other languages. How those words are written in English - as opposed to their native language - may be a bit different but the meaning is close, if not the same as the original.If you are an international student, you may recognize several English words with roots in French. One such noun, government, ranks high on the list of words that are routinely incorrect both in written and spoken English.Native speakers and Esl students alike omit the n in the middle of the word. For proper English speaking, that letter must  be spoken.A handy way to remember how to spell and speak this word is by learning its root and related words: govern, governor, and govern ance. In each of these words, the n is pronounced. Adding the suffix -ment does not remove any of the root word's letters.If you are learning business English, this group of words would be a vital addition to your vocabulary. To study English in depth, you should investigate where tricky words come from.Double Consonant PairsThe list of words with that criterion is rather longer than one would immediately think.MillenniumAccommodateHappinessAggressionOccurrenceEmbarrassAlthough all of these words often stump even native English speakers, only two words on this list are routinely written wrong by natives and non natives alike: accommodate and occurrence.Both of these have their roots in the Latin language, one in which words often feature letter doubling â€" more of consonants than vowels.If you are learning English as a second language, one of the best ways to incorporate proper spelling and speaking of words is to know where they came from and how they were originally used.

Oftentimes, this comes from a local dialect - the way people from a given region use the language.Another portion of blame falls on the growing use of ordinary vocabulary as slang terms. This phenomenon has become so prevalent that there is a website  which regularly updates their list of words misused as slang.In spite of regional dialect or slang usage of any word, as an English learner, you should always spell and use every word correctly. Language learners all over the world naturally gravitate to the most trendy, up-to-date vernacular of the country they are in.The typical native English speaker  admittedly uses many slang words and phrases during the course of everyday conversation, a substantial number of which are born from the entertainment industry.Musicians are especially adept at creating new spelling of words and phrases in an attempt to reflect their new, cool style.

While a spell checker is an excellent tool to catch and point out mistakes, auto-correct could actually impede your progress in mastering English â€" and lower your grade!Imagine you are writing an essay for your english lessons online. Within your text is this sentence: “I leave all of my worldly belongings to my airs.”Your word processing software will not recognize any errors because everything is spelled correctly.Unfortunately, the word you wrote is a homophone for heirs - meaning: people who have a right of inheritance.  For better learning, disable the auto-correct feature on your computer Source: Pixabay Credit: FsHHUsing the wrong  homophone, even though correctly spelled, will result in a spelling error rather a vocabulary error on quizzes and exams.It would be best to add them to your new words list and learn them well, lest they cost you points on your qualification exams.Tips to Help You Improve Your Spelling and Grammar SkillsMemorize word in groups â€" all of the words associated with it, or any word derive d from it.Study this list of most commonly misspelled words put together by Oxford UniversityTake time to discover where the words you are studying come from. Oftentimes, etymology can help you understand why a word is spelled in the fashion it is.Learning prefixes and suffixes can help you understand meanings of words as well as spell them properly.Set your computer's spell check to manual, so that words that need revision will be highlighted, for you to correct by yourself.Disable the auto-correct function in your word processing program.Doing so forces you to develop your spelling and grammar skills without relying on the machine to fix mistakes.Take practice quizzes to challenge your abilities.Going beyond rote memorization of vocabulary by: grouping words into families, by tracing the origin of words, and applying extensions correctly, you are putting yourself on the path of complete, in-depth learning of English and better spelling ability.You can improve your English listenin g skills by downloading and playing podcasts from the British Council website.They are hosted by speakers who use Oxford English, spoken clearly and concisely.

A Parents Guide to Learning in the Digital Age

A Parent's Guide to Learning in the Digital Age The technological advancements of the 21st century have changed nearly all aspects of modern lifeincluding education. Working purely with textbooks, printed maps, and other physical resources was the norm for students until the 1980s and 1990s. Todays students have a myriad of technologies at their fingertips that can make the learning process more captivating and convenient. However, not all devices on the market are equally beneficial to students. So which technologies can help or hinder an early learners growth? See below for a brief guide to learning in the digital age. [RELATED: 3 Emerging EdTech Tools That Can Spark an Interest in Learning] Digital technologies that can help Electronic reading tablets Sometimes seen as cooler than traditional books, electronic reading tablets (such as the Amazon Kindle) can instill an early love of reading in your child. Such devices also make it easy for readers to discover the meanings of new words, take notes, and quickly skip pages. Additional benefits of electronic reading tablets are that they are lightweight and portable. Just take along the tablet and charger on any upcoming trips, and your child will be able to read comfortably from a variety of options. Digital storytelling Digital storytelling is the process of creating an original storybook online. Websites such as Little Bird Tales and Storybird allow young students to use their imaginations as they practice higher thinking skills. Students can also read the digital storybooks of other individuals around the world. In the case of writers block, students may get inspiration from the writing prompts that are also available. With Little Bird Tales, students can even record their voice to narrate their own stories. Both websites offer a free trial so students and parents can decide which is right for them. [RELATED: 5 Benefits of Using Videos to Learn] Digital technologies that can hinder Non-educational video games in excess When played in moderation, age-appropriate video games can serve as an enjoyable outlet for children to destress and, in some cases, get exercise. But video games can quickly become addictive for people of all ages, and children are no exception. Video games should never take away from a childs study, sleep, meal, and family time. Some studies have shown that children who play video games often are slightly more at risk for developing attention problems. Another has revealed that young gamers perform worse on reading tasks than their non-gamer classmatesbut this may be because they substitute after-school reading time with game-playing time. Devices without parental controls Children, who are naturally curious, may turn to the internet for answers to their many and varied questions. While there is nothing unnatural about this behavior, parents should be vigilant about their childrens browsing habits. Any device with internet capability but without parental controls could be a danger for children. A simple online search can unearth inappropriate, violent, and generally traumatizing results for an impressionable child. Opt for preventative solutions, such as apps and software with parental control features built in.

Online Trig Identities Solver Tutors

Online Trig Identities Solver Tutors In Trigonometry, trigonometric identities are very important as they help us understand the relationship between the 6 trigonometric functions in a much better way. Identities are equations where the given trigonometric expression in the left-hand side of the equation is the same as the trigonometric expression in the right-hand side of the equation. Therefore in order to prove trigonometric identities, we must show that the left side and the right side of the equation are exactly the same! Example 1: Prove the trigonometric identity: tan(x) * cosec(x) = sec(x). In order to prove the above given trigonometric identity, we have to first start by picking any side of the equation. Here lets start with the left-hand side of the equation - tan(x) * cosec(x) We can also write the above expression as: tan(x) * cosec(x) = [sin(x)/ cos(x)] * 1/sin(x) Now sin(x) in the numerator and the denominator gets cancelled, which gives - 1/cos(x). So, 1/cos(x) is also written as sec(x) = right-hand side of the equation! Hence proved! Example 2: Prove the given trigonometric identity: tan(x) + sec(x) = [1 + sin(x)] * sec(x). In order to prove the above given trigonometric identity, we have to first start by picking any side of the equation. Here lets start with the left-hand side of the equation -tan(x) + sec(x) We can also write the above expression as: tan(x) + sec(x) = [sin(x/cos(x)] + 1/cos(x). Herecos(x) present in the denominator can be taken as the common denominator. This gives: - [1 + sin(x)]/ cos(x) which is re-written as [1 + sin(x)] * sec(x) =right-hand side of the equation! Hence proved!

Six Reasons to Learn Chemistry (Even if You Dont Want To)

Six Reasons to Learn Chemistry (Even if You Don’t Want To) At AJ Tutoring, we have the privilege to work with many students every year who are engaging with chemistry concepts for the first time. Some are enthused while others are less so. Getting students to see the beauty and order in chemistry is our greatest joy.  If you’d like to learn more about how our chemistry tutors can help you your student with chemistry tutoring, please give us a call today!1. Unit Conversions!Have to switch from dollars to euros? Pounds to kilograms? Need to scale a recipe up or down based on the amount of ingredients you currently have? Worried about the SAT math unit conversion questions? Stoichiometry is all about unit conversions and using a methodical, unit-based approach to convert between units.  2. Improved Cooking Skills  Be it boiling water for a recipe on a camping trip (i.e.understanding how elevation can affect phase changes) or seeing how various ingredients interact, the benefits of chemistry can bolster culinary endeavors.  3. Reading Product Labels  The chemistry student knows that not everything is a “chemical” and that not all synthetic substances (i.e. Advil) are harmful. At the same time, the chemistry student knows that not all “natural” or organic compounds (i.e. formaldehyde) are safe. Chemistry teaches critical thinking skills needed for modern, evidence-based solutions and thoughtful decision-making. Chemistry also facilitates critical thinking skills so that medical marketing is better understood and evaluated.  4. Understanding Chemical SafetyChemistry can give students the background to understand how and why even something as common as household cleaning supplies can be toxic in some cases.  5. It’s the central science!  For students aspiring to study science, chemistry can give them the foundation to better understand other branches of science like biology, physics, earth sciences and medicine.  6. Understanding Climate Science  In the era of climate change, chemistry helps a student become an in formed citizen about terms like acid rain, carbon emissions and ocean acidification. Even if a student does not pursue chemistry beyond high school, developing an understanding of ecological reactions and their ensuing consequences has lasting consequences for future generations.

Interview with Simon Singh

Interview with Simon Singh We had a very special treat yesterday: a visit from Simon Singh! Yes that’s the Simon Singh, science and maths author who has worked for the BBC’s Science and Features Department, directed the BAFTA award-winning documentary ‘Fermat’s Last Theorem’, created education programmes Undergraduate Ambassadors Scheme and the Enigma Project and has written many fantastic books: ‘Fermat’s Last Theorem’, ‘The Code Book’, ‘Big Bang’, ‘Trick or Treatment’ and his latest, ‘The Simpsons and Their Mathematical Secrets’.  Whoa! Simon has a vision to inspire young people with maths and science. In a world that progresses via innovations in maths and science we need more mathematicians, scientists and engineers - and for that, we need more maths and science teachers - and for that, we need more people studying maths and science at university. But how can we make this happen? Simon has some revolutionary ideas about how to nurture and develop students’ talents in maths and science, encouraging them to study these subjects at higher levels. We managed to grab Simon for a little interview at the end of our chat: Tutorfair: Why do you love maths and science? Simon: I think the question is, why wouldn’t you? Science is exciting! Just think about everything that’s been going on with the Big Bang at the moment. It’s fantastic. For maths, it’s a bit different. I originally did maths in order to do science, but after writing a lot about science, I began to see the beauty of maths. Take the number 26: it’s the only number between a squared number (25) and a cubed number (27). Despite the fact that there is an infinite quantity of numbers, we can prove that 26 is the only one. That’s really cool. In maths you can answer the questions, ‘How does that happen?’ and ‘How do we prove it?’ Why did you decide to study Physics at university? I grew up during the space race so I was drawn to the physical sciences. I love learning about the universe. Why do you think it’s important for children to learn maths and science? Maths and science can bring tremendous joy! If they excite you, then they could become your career. But otherwise, maths and science have an impact on our lives â€" they help us understand how things work which is important. Even if your job has nothing to do with science, you will need to vote on issues like climate change or genetic engineering; you will need to decide whether to vaccinate your children and so on. So it’s important to understand the science and maths behind these concepts. We find that children need tutoring the most for maths and science. Why do you think that is? Maths is particularly not natural. Take my son, for instance: he learnt to talk and to walk and a lot of other things, all by himself. But counting did not come naturally; he had to be taught it. The idea of using a symbol to represent something is not natural for him. And maths becomes more and more abstract. Science is a bit different, but it has been argued that it’s also not so natural, making it more difficult to learn. What would your words of wisdom be to kids who are currently struggling with maths or science? They are such important subjects. You need to know the basis of maths and science to be an active citizen so stick at it and you’ll get there. Can you tell us a bit more about the education projects you started â€" the  Undergraduate Ambassadors Scheme (UAS) and the Enigma Project? UAS provides university departments with the framework for a module which awards academic credit for undergraduates studying STEM subjects to work with teachers in local schools. They go into the schools once a week for about 10 weeks. Everyone is happy. The students love getting the experience and the teachers love having the support. The students are learning skills highly valued by employers, and the course is tough, so the academic credits are well deserved. This module runs in about 100 university departments now across the UK. The Enigma project involves me lending my Enigma machine to Cambridge University so that they can take it around schools to run workshops with students about code breaking. It travels throughout the United Kingdom and abroad, visiting over 100 schools and organisations. â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"â€"- As you can see, Simon does some awesome work with STEM in education so it really was the perfect treat to have him visit us during National Science and Engineering Week. Thank you Simon, we look forward to chatting to you again soon. If you’d like some amazing scientists to come to your house try: Alfredo C  - Doing a PhD in how galaxies are formed.

How Parents Can Use the Midyear Report Card to Their Childs Advantage

How Parents Can Use the Midyear Report Card to Their Child’s Advantage With the first half of the school year now finished, its time for a mid-year check-in with first-semester report cards. Although some children dread report card time, Eileen Huntington of Huntington Learning Center encourages parents to ease their childrens concerns. Report cards are a valuable tool and create the opportunity for conversation between parents and their children about how things are going, what issues are of concern and any next steps to address those challenges. Dont just read the report card for a few minutes and file it away, Huntington urges. She offers these tips for using the report card to help your child: Focus on study skills. Grades are certainly important but look for indicators that your child is taking initiative, managing his or her time, focusing and studying effectively. These skills should translate to home as well, so make sure to pay attention to your childs ability to keep track of assignments, prioritize homework and stay organized. Look for evidence of sincere effort. Your childs content knowledge is important, but so is his or her attitude and willingness to work hard. Read comments from the teacher that address this, and if there are none, talk with your child about the time he or she invests into homework each night. Its important that your child gives school his or her best effort, and its also a good idea for you to make sure his or her grades reflect that effort. Highlight any strengths. If a report card has some bad grades or comments, its very easy to focus on that. Give credit where it is due, however. Notice any strengths or areas of improvement from the last report card. Point out subjects where your child is experiencing success and remind him or her that together, you can and will help your child get better in other subjects as well. Take note of progress. If your child received a first term or quarter report card, compare that one to the midyear report card and look for areas where your childs performance has improved or declined. These changes will give you valuable information for your conference with the teacher as well as conversation points for talking with your child. How does he or she feel about each subject? Which causes the most stress and joy and what does your child feel needs to happen to make adjustments before spring semester? Once youve thoroughly assessed the report card, sit down with your child and formulate a plan. This is where the report card can become a powerful tool, Huntington says. Talk with your child about the action you will take together to help your child overcome difficulties and get back on track toward achieving grade-level standards and other goals. The report card gives you critical information about your child, so be sure you use it. If your child is struggling in school and youre not sure how to proceed to help, call Huntington. Well work with you to evaluate your childs abilities and develop a customized, one-to-one program of instruction to turn things around by the end of the year. 1-800-CAN LEARN
