Definition of Reduction Chemistry

Definition of Reduction ChemistryTo define reduction chemistry is to tell the students that this is the field of study in which all the materials are reduced. This includes every substance, it does not only refer to a single type of substances but also to the processes which are used to convert substances into simpler form. Reduction chemistry has many applications and can be very useful for a wide range of people.It is very important to understand what a chemical reaction is before understanding the definition of reduction chemistry. A chemical reaction is a product of an interaction between two or more molecules. It is a change in shape and/or size. A reaction takes place as a result of an application of forces.A chemical can be said to be 'polar' when it has the initial reaction between the two molecules. This is considered to be the reaction of forces between the molecules. The molecules of a polar substance will not separate. An example is water and air.Another good example of a polar substance is hydrogen and oxygen. Hydrogen combines with oxygen to form water. With some other solids, such as salt and grease, this reaction is reversed. A molecule containing hydrogen and oxygen combines with hydrogen to form a mixture of hydrogen and oxygen atoms.There are many different kinds of chemical reactions. Some types include the electrochemical reactions, where charges are moved and the results are different. There are also the physical and thermal reactions, which involve molecules and their energies. The boundaries between different types of reactions are very blurred and are also very important for knowing the definition of reduction chemistry.The structure of a chemical is the way a molecule is composed. There are a number of different structures of a molecule. For example, carbon, oxygen, and hydrogen have different structures. A person can memorize what a carbon molecule looks like, but they cannot memorize how many atoms that carbon molecule contains. They cannot tell you exactly how many atoms there are in a hydrogen molecule, because the hydrogen molecule contains one proton and one electron.Carbon's molecules are the hardest to memorize because they look the same from across the room. There are molecules that look the same from across the room, but they have different shapes and properties. You cannot know how a molecule is going to react until you study its structure.Reducing compounds are the substance that combines with another substance to create a smaller version of the original. For example, ethylene, which is a reducing compound, is made when ethanol is combined with propylene. The original ethylene would not exist without the reducing compound.

My Experience at The University of Chicago

My Experience at The University of Chicago The tutors behind Varsity Tutors are not just here to teachtheyre sharing their college experiences as well. Anindya is a Manhattan tutor and 2010 graduate of The University of Chicago. He holds a Bachelors degree in Law, Letters, and Society, and he tutors several subjects, including algebra tutoring, public speaking tutoring, and writing tutoring. Check out what Anindya had to say about his time at The University of Chicago: Describe the campus setting and transportation options. Anindya: The University of Chicago campus is nestled in a quiet and beautiful part of Hyde Park, just a few miles south of downtown Chicago. The quad is full of seasonal trees and plants, and it is surrounded by a mixture of modern and Gothic buildings. Students have many options to get into the city by bus or train, which takes 20 to 30 minutes. Hyde Park itself is also a vibrant neighborhood with lots of options for food, drink, and leisure. How available are the professors, academic advisers, and teaching assistants at The University of Chicago? Anindya: Professors are available to undergraduate students, but students typically have to take the initiative to contact them either in-person or via email. These professors are world-renowned researchers, but they are willing to take the time if students are not shy about asking. Advisers at The University of Chicago are amazing, and they are very helpful when deciding majors, picking classes, and offering advice for balancing workloads. Teaching assistants are also very helpful as long as students reach out to them for help. How would you describe the dorm liferooms, dining options, location, socialization opportunities with other students? Anindya: Though The University of Chicago may have a bad reputation for being where fun goes to die, this is just a funny slogan that students embrace and are proud of. Most dorms that exist now are modern and luxurious. For first years, dorms largely determine your friends, but there are many student organizations that you can join to meet new people. Food is also great on campusdefinitely a surprising relief. Which majors/programs are best represented and supported? Anindya: The University of Chicago is definitely well renowned for their economics programs. Students who major in economics and graduate with a good GPA should not find it hard to land a great job. I studied Law, Letters, and Society, which is a selective major that offers classes at the law school and is a mix of legal rhetoric and reasoning courses. I recommend applying to it. Even though I am currently in academia and not law, it was worthwhile. 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? Anindya: I found it fairly easy to meet new people and make friends. Orientation week is literally a week of fun activities for students to interact and socialize. I did join a fraternity, but Greek life can be separate and invisible to those who are not interested. Still, Greek life offers an organized way to make lifelong friends and create lasting networks. How helpful is the Career Centerand other student support services at The University of Chicago? Anindya: To be honest, I did not use the Career Center much, but my friends did and found it helpful. Many reputable companies come to job fairs. I took more informal methods to land a job, such as emailing my professors about possible opportunities to work for them. How are the various study areas such aslibraries, the student union, and dorm lounges? Anindya: All facilities are clean and very conducive to productive studying. They only get crowded during finals, but that is a part of the intellectual atmosphere of that time. It is easy to get a personal desk, or to sit at a big table with friends, though silence is usually required at most libraries. Harper Library is gorgeous and looks like the castle in Harry Potter. Describe the surrounding town at The University of Chicago. Anindya: Hyde Park is vibrant and refreshing. Especially during the spring, fall, and summer, there are many street events like art walks. Winter is cool too because there is an ice rink on the Midway two blocks south of the quad. There are awesome restaurants, including upscale or small and cozy diner-type spots. President Obama heartily endorses Valois, but I am a Salonica person myself. Noodles, Cedars, Seven Ten Lanes, and Leonas are also all great hangouts for students. How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Anindya: There are about 1,000 students per class. I think that is the perfect number for small class sizes, and feeling like you know a lot of the people you will graduate with by the end. I only had one or two classes larger than 30 studentsbig lecture coursesand the rest typically had 20 or so. The University of Chicago is very selective about keeping these numbers. Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Anindya: I loved my American Law and the Rhetoric of Race course, which I took at the law school with law school students. It was a very moving experience about how the law changed to finally view African Americans as deserving of rights, and the long and difficult process involved in this. It was taught by Professor Dennis Hutchinson. I regret not having taken his class on Abraham Lincoln, which many others said was their favorite. Check out Anindyas tutoring profile.

GCSE Biology Digestive System, Nutrition and Excretion

GCSE Biology Digestive System, Nutrition and Excretion GCSE Biology Syllabus At A Glance ChaptersGlossary of   Terms for GCSE BiologyNutritionDietDigestionEgestionMaking Biology GCSE Fun: Some Interesting FactsUseful LinksA very large proportion of the GCSE Biology course is focused on the human body, teaching you about the structure and functions that help us to survive day in, day out.This particular area of Biology, related to the digestive system, nutrition, and excretion, covers a wide spectrum of subtopics, however, the two subject matters that are the most directly linked with humans are those linked to diet and digestion. As such, this is what I will focus on in this educational blog aimed at GCSE level students.To help you to follow the biological parts, processes and functions described below, we have provided a glossary of terms, put together by the experts at BBC Bitesize, which can be referred to whilst you read this text, or can be saved for future reference. Go to their website for tonnes more guides, tests and other useful references during your course.No te: Having a list of key terminology can be very useful when you come to revise for your exam, as this topic is likely to come up in at least one question on your paper.Labelled Digestive SystemTake a look at this labelled digestive system. Image sourced from http://freeencyclopedia.wikia.com/wiki/File:Digestive-system-diagram.jpgWhere Is Bile Produced?After being in the stomach, food makes its way to the small intestine where food molecules get into the blood through the wall of the intestine. This is called absorption. Enzymes work best in alkaline conditions, so bile is produced by the liver, stored in the gallbladder  and then released into the small intestine to help to emulsify fats and help the lipases to work more effectively.Digestion and EnzymesAs we've seen, enzymes play an important role in the chemical breakdown of food during digestion. But what exactly are these molecules and how do they do their job?We already know that enzymes work at their best when at their optimu m pH, so they rely heavily on the right conditions being set up for them in the stomach or gut.There are three principal types of enzymes: Protease, Carbohydrase, and Lypase.AbsorptionProtease enzymes are found in the stomach, small intestine and pancreas and their task is to digest proteins. Pepsin is a common type of protease and helps to break down the long chains of amino acid molecules found in proteins into smaller links called peptides and then into individual amino acids which are easier absorbed in the small intestine. You may be required to know the equation for this process which is:proteins -protease- amino acidsCarbohydrase enzymes, as you might expect, break down long starch molecules. They are secreted by the mouth, pancreas and small intestine. One type, named amylase, is found in our saliva and starts doing its work as we chew our food.The first step is to break down the complex starch molecules into maltose molecules (taking them from polysaccharide to disaccharide ) and then it gets broken down again into glucose.The equation is as follows:starch -amylase- maltose -maltase- glucoseLastly, Lipase is found in the pancreas and the walls of the small intestine. Complex fats, called lipids, get broken down into soluble fatty acid and glycerol molecules as indicated in the word equation:lipids -lipse- fatty acids + glycerolA Summary of The Principal Enzymes And Their FunctionsBelow are the main enzymes found in the human digestive system and what they do.Digestive enzyme nameWhere in the body it is producedWhat reaction is catalysedProteaseStomach, small intestine and pancreasTurns protein into amino acidsCarbohydraseSaliva, pancreas and small intestineTurns starch into glucoseLipasePancreas and small intestineTurns fats into fatty acid and glycerolDid you know that the longest part of the small intestine would measure  between 2-4 metres long if laid down flat? The large surface area means that absorption happens quickly, helped by finger-like vil li which further increase the area.What Does The Large Intestine Do In The Digestive System?Different things happen to digested and undigested foods once they have passed through the gut; digested food molecules provide energy and build new proteins in a process called assimilation while indigestible substances reach the colon, the first part of the large intestine.EgestionWhat Does The Rectum Do?Once all of the remaining water has been absorbed, the bacteria and cells (undigested food) that are left become waste, also known as faeces. This semi-solid material is stored in the rectum, which makes up the final part of the large intestine and then gets passed out of the anus in a process called egestion.The rectum provides temporary storage, and it is as the rectal walls expand due to collecting faeces that cause you to feel the need to go to the toilet, or defecate. Peristaltic waves then push the waste out of the rectum.The anus then takes over and controls the expulsion of the faec es, in particular by the anal sphincter muscle. The internal and external muscles relax, allowing the waste to be passed and then by pulling the anus up over the exiting feaces.Egestion, i.e. the process of passing semi-solid waste when you go to the toilet, is not be confused with excretion.Excretion  is the removal of waste products from the body via other organs, like the skin.During your course, you will also learn more about  urine and how this leaves the body in both males and females.Making Biology GCSE Fun: Some Interesting FactsIf all of the above feels a bit scientific and has left your mind a bit frazzled, take a look at the following fun facts and look at the digestive system in more relatable terms.We humans are said to eat about 500 kilograms of food a yearOur bodies produce around 1.7 litres of saliva in just a dayThe standard oesophagus measures around 25 centimetres longEven if you did a handstand, your body would still move the food you ingest down the oesophagus a s the muscles contract like waves to push it in the right directionAn ordinary adult's stomach can hold around 1.5 litres of food and drinkOut of the, roughly, 11.5 litres of food and water you take in in a day, only 100 millilitres is lost in your faeces. You'll learn more about excretion in your classes.Food that enters your mouth is both warmed and cooled to make it the optimum temperature for digestion. So, if you eat food, your mouth will cool it down and if you eat chilled materials, it will bring the temperature up.It's fascinating what our bodies can do and how much work they put in just to keep us alive and well. It is no wonder we need to rest at night! But even while we sleep, our bodies continue to carry out their numerous and momentous tasks...To learn even more than you would do in your classroom or using self-study methods, why not look out for biology a level tutors.Useful LinksAs part of your revision for Biology GCSE, you may wish to brush up on the following topic s:GCSE Biology Syllabus: Topics At A Glance GCSE Biology Revision: Reproduction In Humans GCSE Biology Evolution GCSE Biology Revision: Living Organisms GCSE Biology Revision: Inheritance and Genetics
