Organic Chemistry Theory - What Will It Take?

Organic Chemistry Theory - What Will It Take?Oscillation theory is one of the concepts that you will have to master before you can even think about becoming an organic chemistry tutor. This is because in this topic, it is essential that you understand how oscillation actually works. Even if you are just a beginner in the field of organic chemistry, there is no way that you can go to study the different theories that you will have to master first.One of the most common questions among the organic chemistry tutor community is what will it take for you to be able to apply oscillation theory. As you may already know, one of the most important concepts in organic chemistry is that of oscillation. In fact, it is essential that you become familiar with this concept in order to be able to complete your organic chemistry homework assignments and test papers correctly. To give you a better understanding of the concept, let us discuss it in more detail.Essentially, oscillation is the transition between two physical states. If you wish to delve further into this topic, you should keep in mind that it refers to the gradual increase in kinetic energy of atoms. Atoms do not only occupy one particular state; instead, they occupy a number of different states. Oscillation basically refers to the process whereby the atoms move from one state to another. What makes this phenomenon interesting is that as long as the atoms are in one particular state, it is not necessary for them to oscillate.Oscillation is most commonly linked to the process of equilibrium. According to this concept, when an atom is in a particular state, it is always in equilibrium with another atom in its same state. As such, we can say that there is a position of an atom at which all other atoms are positioned.With oscillation theory, we are talking about atoms that contain many neutrons. These are the atoms that are often referred to as spin-1. The neutrons are also known as the 'leptons' since they do not poss ess a single valence electron. In other words, these atoms have both up and down quarks.As the atoms come in contact with one another, they are either up or down quarks. However, some quarks have extra mass that affects their overall mass. Therefore, there is a difference in the amount of vibrational energy of the various atoms that makes them oscillate.There are two main theories in regard to oscillation. One is the Atomic Bomb (AB) theory and the other is the Schrodinger's Atom (SA) theory. According to the AB theory, electrons and protons are constantly fluctuating as the atom makes its way towards being 'at rest'. On the other hand, the SA theory describes electrons as particles with mass and vibrational energy that remain in their respective states.In the end, you can now tell whether you want to become an organic chemistry tutor or not by knowing whether you are familiar with the concepts and principles that comprise oscillation and equilibrium. It would be best for you to con sult with an organic chemistry tutor before you begin your formal education in this field.

Chemistry Concepts and Problems - Which Types of Compounds Are Normal and Which Are Not?

Chemistry Concepts and Problems - Which Types of Compounds Are Normal and Which Are Not?Chemistry concepts and problems are very important if you are a student that is currently taking chemistry classes. While there are many different types of chemical compounds that have their own definitions, the term 'chemical compound' refers to the chemical elements and other compounds which have the same atoms and molecules but different properties, such as properties such as electronegativity or electrical charge. Therefore, many different compounds can be lumped together under the term compound because they all have properties that are similar in some way.Most of the types of chemical compounds are what you would find in the home, as is the case with most plants. In fact, plants are composed of several chemical compounds that are the same. Some examples of these are cesium chloride and potassium chloride. These are the two components of potassium nitrate and sodium nitrate respectively.One ty pe of compound is hydrazine, which is a compound that is found in some types of the most common compounds found in nature, such as water. This compound is also found in some products and medications, such as dihydrotestosterone (DHT) which is found in some types of prescription male enhancement drugs.So far, there are only two types of chemical compounds that are definitely known to man. They are the alkali metals and alkaline earth metals.The other compounds that we have been discussing are referred to as acid-base compounds. These are the substances that are composed of acids and bases together. These types of compounds are not commonly found in nature, so these compounds are used to produce complex organic materials.There are different ways to learn about basic chemistry concepts and problems. Here are just a few of the different methods:Regardless of the method, if youare interested in learning more about these different types of compounds, then you need to read about them. Ther e are many books and other resources that can help you learn more about these compounds.

Definition Of Acid Chemistry

Definition Of Acid ChemistryIf you have been dealing with any kind of chemistry at all, then you probably know that acid chemistry can be quite interesting. One thing that you may have wondered about is if there are really any definitions or what they are and how they can help you, the student or learner, understand this subject more fully.The most basic definition of an acid is a mixture of hydrogen and carbon. Therefore, if you do some research on the chemistry you will find that these two elements are the main building blocks of everything that exists. The source of the acid comes from the element water. Other useful elements to look for are hydrogen and oxygen which are considering the universal elements.Chemical and physical properties are both built around the laws of electricity and force. It is important to understand these different areas as they are necessary in order to properly do work with these elements in a project.There are many different ways to do different kinds of work with the elements. For example, the use of acids and bases can play a major role in mechanical properties of materials as well as electrical properties. Other forms of acid are in the chemical composition of liquids and solids, specifically in solution and solid compounds, and polymerization.An idea that we can use to understand the concepts of acid chemistry, is to look at some chemical reactions. These are based on the idea that two substances in a certain area are connected together in a certain way. The type of chemicals needed, the temperature at which they are made, and the manner in which they react when made in this way, all is what causes the definition of acid chemistry.The structure of the elements is defined by their atomic mass and specific gravity. The molecular weight of a substance also determines how many molecules that it has in it. There are many different forms of each element in this order and the classifications of the chemical elements that they fall und er can help you gain insight into how they form, what they are made up of, and how they work in different situations. This information is important to have and it can come in handy in a lot of different situations.Learning the definition of acid chemistry, and knowing how it can affect the process of chemical reactions and building materials is a good way to get a better understanding of your learning. One way that you can see how this can help you is that the understanding of how acids and bases interact can make a difference in the design of some chemicals and materials. Therefore, taking a look at the definition of acid chemistry and trying to make sense of it can help you to see the relevance in it.

3 Often-Overlooked Parts of a Successful Vocal Performance

3 Often-Overlooked Parts of a Successful Vocal Performance Suzy S. Stage presence makes a huge difference in how your audience will respond to you. Take a look at these performance tips from NY music teacher  Nadia B... You’ve practiced, rehearsed, and it’s finally time to share your vocal arts with others. Sometimes, though, components of a successful performance can be overlooked after you’ve spent so much time mastering the music. Key elements of stage presence for singers include setting a unique musical intention, making use of physical space and gestures, and creating connection in the moments directly before and after you sing, all of which will guarantee that you create an unforgettable and enjoyable performance. Establishing Your Musical Intention What makes live performance enjoyable is the spontaneity created by the performer-audience connection. It can never be the same twice. You can take advantage of this fact by taking a moment before your performance, or in the rehearsals leading up to your performance, to set a unique musical intention. What is a desired feeling you want to convey in each piece, in this performance? You can take into account the audience makeup (is it children, friends and family, judges of a singing competition, or the general public?), and the personal significance of the music for you. Setting this intention will ensure that your performance is meaningful and spontaneous, since you are interacting with the aesthetic of the music in a current and engaged way. Making Use of Physical Space Another element that differentiates stage presence for singers from other musicians is that singers are in a unique position to make use of physical space, both within their own bodies and in the environment. For this reason, an important part of your performance as a singer is to consider the physical possibilities. Are there certain times that movement would emphasize the musical setting or mood? Also consider physical gestures as a way to underline the key musical characteristics of each piece. If youre not sure what to do with your hands or body while singing, check out the helpful tips in this video: Sometimes simply becoming aware of the space around you is enough â€" even if you don’t incorporate movement or gestures, this awareness can allow you to fully expand into the space physically, energetically, and vocally. Creating a Connection With Your Audience Lastly, consider the first and last things you do in your singing performance: you greet and express your gratitude toward the audience for sharing your musical journey with you. These moments play a key part in creating a well-rounded performance. When you enter the stage, a sincere bow can establish an immediate connection with your listeners, and taking your time as you walk along the stage, bow, and prepare to begin singing can allow your audience to settle in and join your journey with ease.  A rushed or nervous entrance can draw the attention away from the music and unsettle the audience. At the end of the performance, a gracious bow allows the audience to fully savor and participate in your performance. They are thrilled that you have performed for them, and it is a sign of respect to acknowledge the pleasure and gratitude that they express with their applause. If you are unsure of how your stage presence is, try turning on an applause track on YouTube at home and working on entering and exiting the room. You can also watch performances of famous singers to see how they interact with the audience to get ideas. Remember that your musical preparation and practice will help you have your best performance possible. Keeping in mind these other elements will only serve to showcase your hard work and skill, and developing a confident stage presence can make the difference between a good performance and an unforgettable performance, both for you and your listeners!

Ask a Medical School Admissions Expert Dr. Carleen Eaton

Ask a Medical School Admissions Expert Dr. Carleen Eaton Varsity Tutors brings you insider tips and advice straight from nationally recognized admissions experts. Dr. Carleen Eaton is a graduate of the UCLASchool of Medicine with nine years of experience in admissions advising. She has helped hundreds of medical school applicants get into their desired programs over the years and has frequently been a guest speaker at various colleges and universities on the subject. Dr. Eaton is the founder of PreHealthAdvising.com, an admissions consulting firm dedicated to assisting students in the medical school application process. She is currently working on her book, Getting into Medical School For Dummies, an installment of the popular series that will be released in May 2013. VT: How much time should be set aside to adequately prepare for and complete a Med School application? Carleen: Some steps should be started at least six months prior to the opening of the admissions cycle. These include researching schools, reading about the application process, and determining whom to ask for letters of recommendation. When it comes to filling out the primary application, the single most time-consuming task is writing the personal statement. Crafting an effective, compelling statement usually takes more than a month. Exactly how far in advance of the submission date an applicant needs to start work on the application depends on how many other things theyre juggling. For example, if an applicant is balancing a full load of classes, extracurricular activities, and MCAT studying, they need to begin working on the application many months in advance in order to spread out their workload. VT: What is the single most important thing applicants should focus on with this application? Carleen: Although every part of the application is important, when it comes to the primary application, the personal statement is crucial. The personal statement allows an applicant to tell his or her story and is an opportunity to let the committee know who they are beyond academic accomplishments and extracurricular activities. A strong personal statement wont make up for a weak GPA or subpar MCAT score, but if an applicant has solid academic credentials, the personal statement can help him or her distinguish themselves from other applicants who are similarly qualified. VT: What are the biggest mistakes one can make on a Med School application? Carleen: A major, and avoidable, mistake applicants make is submitting an application late in the cycle. Most medical school use rolling admissions, which means that they review applications as they are received, rather than waiting until the application deadline to begin their review. Earlier applicants have a much greater potential to receive an interview while there are still plenty of seats open in the class. As the cycle progresses and seats in the class are filled, applicants are competing for fewer slots and may even be interviewing for a place on the waitlist because the class is already full. Applicants should aim to complete every step of the application process - primary, secondary, and interview - as early as possible in order to maximize their chance of admission. VT: What do Med School admissions officers look for most in an applicants essays/personal statements? Carleen: Admissions committees are looking for applicants who are highly motivated to pursue a career in medicine, who have explored the field thoroughly, and who possess the compassion, drive, interpersonal skills and personal qualities needed to become a great physician The most effective way to convey ones message through the personal statement is to follow the tried-and-true advice to show dont tell by using details and examples to convey ones points rather than relying solely on direct explanation. VT: Is there anything on a students application that would automatically disqualify them from being considered for the program? Carleen: Because most schools receive thousands of applications, many schools do an initial screening based on MCAT scores and GPA. Only those applicants with MCAT scores and GPAs that are above a given threshold may receive a full review and consideration for an interview offer. The admissions process differs from school to school, and some schools do a holistic review of all applications; however, applicants with a low GPA and/or MCAT score may find themselves unable to get beyond the initial stage of the application process at many schools. VT: What about the Med School admissions process differs the most from undergraduate admissions? Carleen: The admissions process to medical school has a much longer timeline than undergraduate admissions. An applicant who plans attend medical school directly after college will submit their application the summer after their junior year in college. After the primary application comes supplemental or secondary applications and then interviews. Although most interviews are conducted from September through January, some schools continue interviewing into March or even early April, which results in a process that can take close to a year from start to finish. VT: What undergrad majors best prepare one for med school applications? Carleen: A premedical student can choose any major as long as they complete the prerequisite coursework for medical school. In addition to core science classes that are required for admission to medical school, many schools have a list of additional, recommended science classes that they prefer for students to take prior to entering medical school. It is much easier for a science major to work these courses into their schedules because they often overlap with courses that are required for graduation in that major. Therefore, non-science majors can be at a disadvantage because they tend to have fewer of these recommended courses and less depth in their science coursework. At the same time, being an art history, Spanish, or political science major, for example, will help an applicant to stand out among the sea of biological science majors, which can provide an advantage in the application process. VT: Is there anything you might see on a students application that would quickly put them ahead in the running? Carleen: A high MCAT score. The importance of the MCAT cannot be overstated, although even a student with a great MCAT score may not be admitted if he or she lacks clinical experience or has other deficiencies in the application. If an applicant scores in the mid-thirties or above and has an otherwise strong application he or she is in the running for top-tier schools. VT: What advice do you have regarding MCAT test prep? Carleen: I recommend integrating practice questions into ones study routine very early on. This is more effective than spending months reading and memorizing, saving practice questions until the last few weeks before test day. Also, test-takers should focus on their weakest areas first. These are the subjects that they have the most room to improve on, and although its more enjoyable to study a subject one is good at, the area that one has most difficulty with is the one they should invest the most time in. Finally, dont overlook Verbal Reasoning! Schools take the score on this section seriously, but the temptation for many students is to spend most of their time studying for the science sections to the detriment of Verbal Reasoning. VT: What do Med School admissions officers look for in recommendation letters? Carleen: Admissions officers want to see evidence that the person writing the letter knows an applicant well enough to give a meaningful evaluation. The letter should state the capacity in which the writer knows an applicant and use concrete examples to illustrate the applicants personal qualities, problem-solving abilities, maturity, and other characteristics important for a future physician. Ideally, a letter of recommendation will also provide information that gives the committee an understanding of how the applicant performed compared to his or her peers in the setting within which the evaluator worked with the applicant.

Dividing Radicals

Dividing Radicals Dividing radicals is a way of simplifying rational expression into an expression without any radical in the denominator. It is done by rationalizing the denominator. Rationalizing is a process that starts with a fraction having radical in the denominator and determining a fraction without any radical in the denominator. If both dividend and divisor has radical then divide the numbers outside the radical and divide the numbers inside the radicals. The following example shows how to divide the radicals. Example 1: Simplify: 12 / (32) Solution: Given fraction: 12 / (32) This fraction has radical in the divisor. Rationalize the denominator, dividing by 2 on both sides 12 / (32) = (12 * 2)/ (32) * 2 = (12/3) * (2 / 22) = 4 * 2 / 2 = 25 Therefore 12 / (32) = 25. Example 2: Simplify: (1524) / (32) Solution: In the given fraction both numerator and denominator has radicals. So, divide the numbers outside the radical and divide the numbers inside the radicals separately. (1524) / (32) = (15 / 3) (24 / 2) = 512. This 12 can be written as 4 * 3 = 23 Therefore, (1524) / (32) = 5 * 23 = 103. Example 3: Simplify: 24 / 18 Solution: In the given, the numbers are inside the radical Divide the numbers inside the radicals by 2 24 / 18 = (24/2) / (18/2) = 12 / 9 We know 9 = 3 and 12 = 4. 3 = 2 3 Hence, 12 / 9 = 2 3 / 3 Therefore, 24 / 18 = (23) / 3
