Definition of Oxidation in Chemistry

Definition of Oxidation in ChemistryOxidation in chemistry is the process that breaks down a chemical compound. The chemical is converted into the opposite compound. Many people mistakenly think that this process breaks down the molecules, which they believe give it its oxidation. However, oxidation is a word that we should probably avoid since we are all aware of the wonderful chemical elements that react with oxygen in the atmosphere to produce various forms of highly toxic gas.The term oxidation in chemistry, a combination of oxidation and reduction, is a word used to describe the reaction of a chemical element with oxygen. In order for this reaction to occur, the reaction must begin with a loss of electrons (electron - electron). Oxygen has an electrical charge, which gives it an oxidation potential, which is expressed as the is in units called molecular weight.Oxygen has a molecular structure which is mostly water, but some oxygen atoms have negative charges that will attach the mselves to the positively charged atoms in the molecular structure of the other element. This then creates bonds between the two elements, with the result that the oxygen atom is reduced to the negatively charged oxygen atom of the opposite element. Sometimes the oxygen atom has already been reduced to the opposite element, which is what occurs when the element and the oxidizing agent bond together.Thus an electron is freed from the oxygen atom by a chemical reaction in which the reduction of oxygen to hydrogen and back again releases a radical oxygen. This radical has the potential to be released by the catalyst, which is essentially an element that helps to neutralize the radicals produced by the oxidation process. Thus, the reaction takes place, the hydrogen is used to form water and the water is recycled to the initial chemical form of the product.Oxidation in chemistry is not limited to carbon-based chemicals, although it may occur with carbon-based compounds when there is a ch emical reaction involving one of these molecules. Oxidation is also a property of water, which is something we really should get used to since the environment could use the hydrogen that comes from water to power more efficient cars and other forms of energy production.While hydrogen does have some of the characteristics of oxygen, it cannot be oxidized by oxygen. This means that if there is some kind of reaction that involves hydrogen, then there will be a reduction reaction that produces more hydrogen than oxygen.Oxidation in chemistry is a chemical reaction that can occur even at room temperature. It is the main element in organic chemistry and most commonly occurs when the reaction of a chemical element takes place, which is typically the release of oxygen from one element to another.

Irvine AP Tutor 4 Reasons You Should Form an AP Study Group

Irvine AP Tutor 4 Reasons You Should Form an AP Study Group Tips from a Private Irvine AP Tutor: 4 Reasons You Should Form an AP Study Group ASAP Tips from a Private Irvine AP Tutor: 4 Reasons You Should Form an AP Study Group ASAP Now that the second semester is in full swing students should be thinking about their AP test prep. Of course, students have been in their AP class the whole year, but now the actual exam is not that far away. Students should be prepared for a full day of testing and prepare themselves for the task at hand by working with their dedicated peers. Unfortunately, many students start their test prep way too late and end up having an anxiety attack over May testing. If students start soon, they can avoid a fair portion of their anxiety through preparation and perseverance dont wait another minute to book your Irvine AP test prep tutor. 1. You know your peers strengths and weaknesses At this point in the school year, it should be clear who is truly dedicated to their AP study and who has developed excellent study skills. Get together with your classmates and look at who can complement one another. For example, perhaps one student is great at analyzing obscure poetry while another has a knack for solving tough calculus problems. Whether youre all in the same course or taking multiple AP courses together, its important to play off each other’s strengths so you can all improve. Remember, the AP exam is graded on a straight scale so it’s possible for everybody to get a 5. 2. Study and review The AP test can cover anything from the entire year as well as from material provided by the College Board. It can be difficult to remember something you learned back in the fall, so its important to split up the tasks of study and review. Attempting to make 500 vocab flashcards is entirely overwhelming for one student but may be possible for a group of five to split. Remembering all of those advanced math formulas might be really tough but, again, when split up between five or six people it wont be that bad. Many students focus on only new material and forget to review. Thus, study groups are essential in this area (READ: Ask a Nerd! Taking the AP Exam). 3. Studying the test prep book AP students are strongly encouraged to get at least one test prep book to help them prepare for the exam. Remember, test prep in any area is its own subject and different from the course itself. Learning to fill in bubbles on an English exam is different from actually knowing English. Test prep will have to be conducted above and beyond content learning. When students work together and study the test prep book they can go through all of the tips and tricks together to figure out how to beat that standardized test. Additionally, many students get frustrated and skip over much of the commentary in their test prep book, much of which contains very useful information. When in a study group, these tasks can be allocated to different members in smaller portions making it easier to complete (READ: SAT and AP Exam Survival Guide). 4. Moral support High school students, especially seniors with other things on their mind, can find it easy to forgo AP study for more exciting activities. However, this can be detrimental to their overall GPA and their college admissions. When students meet once a week or so with their study group they will be holding themselves and each other accountable for any work that needed to get done. Also, when a member of the group is becoming overly stressed out the other members can help by providing moral support and by acting as cheerleaders. Each and every high school student in an AP class will become overwhelmed with the volume of study at some point. Having friends and classmates who are in the same position can be really helpful as a reminder to keep your eye on the prize and remember that an exciting college experience is just around the corner.

Ask yourself how much can I achieve in the next 2 hours? instead of Can I complete all tasks? In this way you do not get as easily overwhelmed by the volume of study you need to do. Stop sabotaging  yourself by watching  just one more episode of your favorite TV show, playing  just one more video game, posting just one more picture on Instagram, etc. The sooner you start, the sooner youll get things done and the more free time youll have in the long run. Reward yourself! Set yourself a goal  and determine an appropriate reward once the objective is accomplished.

Introducing a Parents Tutoring Club to Your Family

Introducing a Parents' Tutoring Club to Your FamilyIf you are a parent who has never sat in on a parents' meeting or who would like to make an impact on the lives of your children, consider joining a tutoring club for your children. This is a great way to bring together parents and teachers, motivate them and provide an excellent opportunity to promote good family relationships. In addition, it provides an excellent way to get a much needed break from the stresses of life.Clubs of parents and teachers can help both to increase the frequency of parent-teacher meetings and to obtain additional resources for your child's education. In addition, it will allow you to create a team atmosphere where your children feel that they are being cared for and valued.Most parents who participate in this type of group know that it is important to spend quality time with their children, often at the end of the day when they can get most out of their day. By joining a tutoring club, you will not only b e giving your children the love and attention they need but you will also have some fun while doing it.Another reason why parents want to attend such a meeting is because they want to provide support to other parents who may be teaching their children at the same time. These meetings provide a great opportunity to build relationships with each other and to develop trust in each other. You will also have the opportunity to take a break from your busy schedule and meet other parents who want to build healthy relationships with their children.You will be able to browse through the tutor's online list, get more information about them and arrange to see if they are available to teach your child. If you do decide to join a tutoring club, you can choose to schedule a first visit for one or two classes. The first session will usually last only half an hour and you will often find that you are very interested in the lessons that the teacher has to offer.After the first session, you will be a ble to continue to visit their site for each succeeding tutor and stay in touch with each person's strengths and weaknesses as you try to develop a good working relationship. Once you have had the opportunity to visit their site and compare the teaching style and philosophy of each tutor, you will probably find that you like and trust most of them.In addition, you will find that your children will often benefit from the shared experiences and relationships that you have developed with your other parent and teacher. In the end, a tutoring club for parents and teachers is an excellent opportunity to provide valuable support and love to children.
