Distillation Organic Chemistry in Todays World

Distillation Organic Chemistry in Today's WorldDistillation is a method used by organic chemists to separate liquids and solids by the passage of heated vapors through a filter. The process is based on the principle that the mass of the liquid stays the same while the amount of the solid remains different.Distillation works well for many purposes including drug development, pharmaceutical testing, and extracting water from liquids. It has proved its worth in these areas because it has enabled the chemicals to be separated in their purest form. This would have been impossible without the addition of the distillation process. Here are a few of the ways it can help organic chemists.Phytochemicals. The production of these chemicals takes place in small amounts in nature and only happens occasionally. However, with distillation they can be extracted at a much higher rate.Oil Extraction. With the growing use of fossil fuels, the production of some compounds has been severely affected. In t his case, distillation provides an alternative method for extraction that is less environmentally harmful.Carbon Dioxide (CO2). In the normal cycle of nature, the CO2 created by photosynthesis is recycled back into the atmosphere. When this happens, the CO2 in the air becomes a pollutant and is converted into other gases such as CO2.Ocean Water. When oil is extracted from underground sources, the deposits are usually heavily mineralized. However, with distillation, the water which is produced in this way can be removed from the deposits and used to fertilize various types of plants.When used correctly, distillation can provide a solution to a complex chemical problem. The different methods it is applied to range from those in the pharmaceutical industry to those used for industrial processing.

How Often Should You Practice Spanish To Really Improve

How Often Should You Practice Spanish To Really Improve Maile Proctor Not sure if youre practicing Spanish enough to reach your goals? Make sure youre getting enough practice time with these tips from Spanish teacher Emmanuel N The fastest way to learn Spanish is to practice and use the language as much as possible. Think about it, kids go to school five days a week from kindergarten to high school, and they use English constantly. They read, write, and learn new words and vocabulary. In order to learn a new language, you have to practice speaking, writing, and reading. You might be wondering whats the fastest way to learn Spanish, and the answer is that it depends on how often you practice and use the language. So how often do you need to practice in order to improve? My recommendation: Every. Single. Day. Find Time to Practice I realize not everyone is able (or even willing) to practice every day, but it really is the fastest way to learn Spanish. If you want to learn and improve, you need to make a commitment and find time to practice. When it comes to Spanish, just like any other skill, practice is the key to learning. This doesnt mean you need to study constantly or complete limitless assignments and homework. Make Learning Fun Learning Spanish can be fun, and its important to find a study strategy that works for you. Here are two effective learning strategies that you can try. Listen (and sing along if you want) to Spanish songs. Find videos on YouTube that have English translations for the Spanish lyrics. You can also do this yourself: find the Spanish lyrics and use Google to translate the words. This will be easier if you understand Spanish expressions, and the best way to learn this is through conversations. Watch Spanish shows and movies, or English shows and movies that are translated in Spanish. If youre a beginner, turn on the English subtitles to help you follow along. It may be difficult to understand the shows at first since fluent Spanish speakers speak pretty fast, but youll be able to understand more words and phrases as you continue to practice. Find a Teacher I have shared some ideas and suggestions to help you improve your Spanish, but at the end of the day it always helps to have someone to help you study. Not everyone has Spanish-speaking friends or relatives. This is where a Spanish  tutor  can help. I like to structure my Spanish lessons like conversations you would have with a Spanish-speaking friend. I understand that learning a new language is difficult, and I try to encourage my students when they make mistakes. A teacher can offer extra help if youre struggling, and help you determine what you want to learn and practice. Do Your Homework! Im a firm believer in homework as a study tool. Just because the lesson is over, doesnt mean you’re done learning. Here are some things you can do on your own to practice your Spanish between lessons. Write (in Spanish) about your day, week, or weekend. Write down all the Spanish words you hear during the day that you dont understand. Ask your teacher to explain the words in your next lesson. Watch your favorite show and describe the plot in Spanish. Im Latino, but English was my main language because I used it in school. After years of practicing with my family, I managed to improve my Spanish. Im not fluent and I may not have the perfect accent, but I never gave up on learning. I encourage you to do the same to learn Spanish; challenge yourself, stick with it, and have fun! Emmanuel M. teaches Spanish online.

3D Shapes

3D Shapes 3D is the three dimensional shapes in geometry which is a solid and bounded by length, breadth and height like the room has length, breadth as well as height of the room is a 3D shapes, book, box, pencil, pots all are the example of 3D shapes. Examples of 3D shapes: - Pyramid Prism A pyramid is a solid bounded by plane faces; one of its faces is a polygon of any number of sides and the other faces are triangles whose bases are the sides of the polygon and which meet at a common point outside the plane of the polygon. The plane face which is a polygon, is called the base of the pyramid and the triangular faces are its lateral faces. The common point at which the lateral faces meet is called its vertex. The straight line in which adjacent faces intersect called the edges (or lateral edges) of the pyramid. The perpendicular distance from the vertex to the plane of the base is called the height (or altitude) of the pyramid. The area of the slant surface of the right pyramid= (1/2 ) x perimeter of the base x slant height Area of the whole surface of the right pyramid =area of its slant surface + the area of its base. Volume of the right pyramid= (1/3) x area of the base x height. A prismis a solid bounded by a number of plane faces; its two faces, called the ends, are congruent parallel plane polygon and other called the side faces.

The Health Benefits Of Becoming a Vegetarian

ChaptersCan We Survive On Simply Eating Fruit And Veg?Why Aren't More People Going Meatless?The Health Benefits Behind VegetarianismVegetarianism is a term that we are very familiar with in modern society, but how long has it been around for? And are experts able to confidently prove that it has positive effects on our bodies? Are there really benefits to our bodies if we avoid dairy products, meat and fish? Can we really get all our vitamins, nutrients and plant protein from a vegetarian diet?If you are interested in the history of the vegetarian movement, take a look at this related blog: The History Of Vegetarianism.Below, I will uncover the health benefits that are said to come from becoming a vegetarian.

Photo credit: Dark Dwarf on Visual HuntWhilst  famine and disease prevailed during World War II, meat became a luxury for the rich and so, for many years, we ate nothing but food that was grown in the ground.This just goes to show that a vegetarian lifestyle really is nutritious enough t o keep us going. Not only that, it fed the mouths of a nation going through some of the toughest physical and psychological conditions known to man - which indicates that it also gave them the strength they needed to get out of their living nightmare.This begs the question, therefore,  why are so many of us still eating meat almost every day of the week?It is encouraging to see the recent rise in allotments or vegetable gardens.With gardens now being quite a statement for many homeowners, the idea of being self-sufficient also appeals to the masses. This is why we see so many people on televised gardening shows longing for raised beds so that they can grow herbs and vegetables to use in their cooking.Why Aren't More People Going Meatless?I think that, ironically, the psychology that meat was once a food that only the rich could afford to buy has led to us eating more meat than we need to (because, as we know, a meat-free diet does offer the body what it needs). This is no doubt beca use we want to live in the best way possible and treat ourselves to nice things. Now that meat has been made affordable to all, we just can't help ourselves and continue to buy it because everyone around us is.Imagine a world where 90% of the population was  completely meat-free, how would you feel being one of the minority going into the shop to buy your steak with everyone's eyes on you? This doesn't mean to say that vegetarians look down upon meat-eaters, still they don't agree with their carnivorous eating habits.That said, I strongly believe that meat-eaters do not eat flesh from animals because they see the creatures as a lower class of species to them. There is no spitefulness to the act of meat eating. I think that those who adopt a traditional western diet simply don't think about the food they are eating in any depth, other than to consider which flavour combinations go well. Or perhaps it is that they don't want to think about it...Most meat-eaters don't tend to think abo ut how the animal meets its end. Photo credit:  Visual HuntMost people, especially animal lovers, will agree entirely that there should be rules against cruelty to animals yet they will continue to eat from them because that is what they are used to.If you are brought up in a household that eats meat day in, day out, it can be quite a daunting idea to cut it out from your diet entirely.The Health Benefits Behind VegetarianismThere are many scientific health benefits to adopting a vegetarian diet, which I will go on to list below, but one of the main and perhaps most important is purely the good it has on the soul.By not playing a part in the slaughter of animals, whether brutal or sensitive, our conscience can remain clear and we can feel like we are doing our bit to contribute to saving animals' lives.If a guilt-free life isn’t enough to sway you, then here are some facts on how a meat-free diet can benefit you physically, too.Eating food that is naturally low in saturated fat h as been proven to protect our bodies from debilitating or worse, terminal, illnesses and diseases such as heart disease, gall stones, hypertension, coronary heart attack and some diet-related cancers.Just as you’d expect, this low-fat diet also helps to keep our bodies in shape, resulting in a leaner and more toned figure. The cause of this is fewer calories entering our stomach, coming from power foods like grains, seeds, nuts, fruits and vegetables, providing a good source of fibre and calcium in place of heavy proteins and carbohydrates (did you know that a fibre-rich meal keeps you feeling fuller for longer?).What people may not realise, however, is that it is not only the muscles and bones that benefit from vegetarianism. Experts say that vegetarian living often results in better vision and less skin degeneration â€" which effectively means that by going vegetarian, you could be winding back the years!Of course, there is one other very important part of the body that benefits : the brain. Balanced eating, a healthy body and feeling good in oneself are very important factors in supporting the health of your brain.With so many great effects on the body and mind, it is no wonder that athletes often choose to adopt a strict vegetarian diet, either permanently or to get them for before a game, race, match or other competition.Many classes focus on vegetarianism so why not join one of these cooking courses.Vegetarian Diets For Weight LossIf you are looking to become a vegetarian to better yourself and lose weight for your own self-confidence, then you might be interested to know that Slimming World offer vegetarian meal plans as well, which can be followed any time of the year (as can those provided by the National Vegetarian Week campaign, if you so wish!).Their 7-day recipe ideas will take all the hard work out of meal planning, so all you need to do is cook and enjoy the amazing, guilt-free food.Organisations like Slimming World can help you to plan your we ekly meals.

The idea is to highlight the benefits of vegetarianism by encouraging others to try it out.If this interests you, or you want to invite a friend to join you eating meat-free food, then you can sign up for the campaign's newsletters which will be packed full of fantastic recipes, helpful information and competitions throughout the course of the week.This campaign is similar to the Veganuary one, set up to encourage people to go vegan for the month of January.I recently heard someone talking of Veguary too which, as far as I can tell, is the February equivalent of Veganuary, but for veggies.But you don't have to wait for one of the campaigns - go vegetarian today if it is something you have thought care fully about. You won't look back, I swear! And if you need some inspiration, there are many food bloggers who offer great recipe ideas.Further ReadingFor more interesting facts about vegetarian cooking, see the following blogs:  Tips To Be A Healthy Vegetarian

New York University A Student Perspective

New York University A Student Perspective The tutors behind Varsity Tutors are not just here to teachtheyre sharing their college experiences as well. Casey is a sophomore at New York University studying psychology. She specializes in trigonometry tutoring, psychology tutoring, and several other subjects. See what she had to say about her experience at New York University: Describe the campus setting and transportation options. Casey: New York University prides itself on being in and of the city. Its located in Washington Square Park in the middle of Manhattan. Since our campus is around Washington Square Park, its very urban, but we have plenty of green space and trees as well. There are free NYU buses to take students from the farther away upperclassman dorms downtown, but everything on campus is maybe a 10 minute walk away, at most. If you need to get around, New York has such a vast transit system that nobody has a car. Theres a bike share program that I dont use, but Ive heard its wonderful. How available are the professors, academic advisers, and teaching assistants? Casey: The professors are amazingly helpful theyre mandated to have office hours, and if those dont work for you, theyll work around your schedule. TAs are the same, and the TAs Ive had classes for are so caring about their students. My academic advisor has been a lifesaver throughout the registration processes and the day-to-day little problems that come up. They only have a handful of students, so you can go to them for just about everything. How would you describe the dorm liferooms, dining options, location, socialization opportunities with other students at New York University? Casey: Dorm life at NYU is such a great environment. The freshman dorms are freshman-only and build such a community between students. Our RAs took us on amazing trips and I befriended almost every of the forty-something people on my floor. Most of the dorms are feet away from classes, but some of the upperclassman dorms are a short walk, 15 minutes at most. There are dining halls in many of the dorms, but nobody is too far away from food. There are apartment-style suites with kitchenettes, as well as traditional style dorms that dont have a kitchen. One thing Ive loved about NYU dorming is that every single room has its own bathroom; that means no communal showers. Which majors/programs are best represented and supported? Casey: NYU has virtually every major imaginable and even a school for students who wish to create their own major. There are dozens of support options and career counseling options available to every student, regardless of what they are trying to pursue. I am studying Psychology at the College of Arts and Sciences and Cinema Studies, which is a cross-school major with the College of Arts and Sciences and Tisch School of the Arts. All of the majors have their own advising network of academic advisors and accredited professors. Ive been very satisfied with the support I have gotten. How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Casey: Making friends as a freshman was a little scary the first day or two, but it was extremely easy to meet people. I met my best friend by complimenting her skirt when I saw her in the elevator, and weve been inseparable ever since. NYU isnt that big on Greek Life, but I know a handful of people who are involved, and they highly recommend it. How helpful is the Career Centerand other student support services at New York University? Casey: The career center is amazing and has been pivotal for me in securing internships. NYU has such a vast alumni network that wants to recruit undergrads for every area imaginable. There are so many student support services. There is peer tutoring, skill-building services, and study slams for every subject imaginable. There are great support services for diverse student groups at NYU, such as resources for LGBTQ+ students and the Moses Center for Disabilities. NYU has a center for physical and mental health, as well as a 24-hour Wellness Center helpline. They offer regular checkups for various health concerns as well as flu shots and the like. Theres also so many resources for mental health at NYU, including meditation and yoga classes. How are the various study areas such aslibraries, the student union, and dorm lounges? Casey: NYUs library is beautiful. Its a gigantic building, and Ive always found a place to study (even during finals). There are student lounges in almost every classroom, in the student center, and every dorm that provide a great space to hang out or get work done. Describe the surrounding town. Casey: NYUs surrounding town is New York City. Theres always stuff to do from a Broadway show, to sports games, to awesome food and nightlife options. Youll never be bored! How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Casey: NYUs student body is around 20,000 students, but it feels a lot smaller. My class sizes ranged from lecture halls to 10 person seminars. As it is at most colleges, class size gets smaller as you get past the introductory classes. Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Casey: One of my favorite classes was my freshman year seminar. The professor, Eddy, taught me and ten other freshman for the semester and we all became so close. The class was on film and television in the U.S., and it ranged from the 40s to the present. This class encouraged me to follow my passions and study the subjects that interest me. I am still in contact with the professor to this day. Check out Caseys tutoring profile.

A tutors guide to choosing the right school for your child

A tutor's guide to choosing the right school for your child For students and parents, it can often be a stressful experience choosing which school to go to, especially when in some cases there can be many to choose from.   Here, Vishal N, one of our 11+ tutors with several years of experience, gives his top three factors to consider when choosing a school. Choosing the right school 1. Location, location, location! This is often the most neglected factor when it comes to choosing the right school. If you live in Harrow and decide to apply for Whitgift (London), you are looking at a travel time of a minimum of 1 hour and 15 minutes â€" and this doesn’t even take into account any traffic. Not only can this be a stressful journey for parents, but can often take its toll on the child who arrives at school fatigued and not in the mood to learn. 2. Whether or not your child can cope with the pressure As we all know, not all children are the same! Just as some children prefer football over music, some children can work well with pressure from teachers and constant mini-tests on a weekly basis, whilst others may begin to dislike school and everything associated with it. Therefore, knowing whether your child enjoys dealing with pressure and always having to be compete academically with his/her peers is imperative when choosing the right school. Some schools are certainly more academically challenging than others. 3. The atmosphere and how you feel whilst visiting the school One of the most important things is to visit the school on open days. This is a fantastic opportunity to not only meet the teachers and ask questions, but it also allows your child to soak in the atmosphere and helps them imagine how they would feel studying in the school for the foreseeable future. Vishal is one of our experienced 7+, 10+, 11+, 13+, 16+, Common Entrance, Admissions and GCSE tutors. He covers Maths, English and Science and has helped many students prepare for competitive entrance exams at a range of schools.
