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!
