What Is Organic Chemistry?

What Is Organic Chemistry?Organic chemistry is a subfield of chemistry, in which the chemical components are synthesized using natural processes without using the help of man. An example of organic chemistry is based on the concept of simple oxidation of hydrogen peroxide, H 2 O. The catalyst reacts with the hydrogen peroxide to form a mixture that undergoes oxidation. This reaction is the basis of the reactions used in organic chemistry.In the course of organic chemistry, catalysts play an important role in the reaction process. The most common catalyst used in organic chemistry is sulfur. Another popular catalyst in organic chemistry is peroxide. Peroxide, which reacts with hydrogen peroxide to form hydroxide, is commonly used as an oxidizing agent for organic reactions.Another type of catalyst used in organic chemistry is the peroxide/metal complex, which functions by reducing the peroxide, with the aid of the metal compound (usually iron or sulfur). Another popular catalytic agen t in organic chemistry is bromine. This product is used as a catalyst by many organic chemists.One important property of organic chemistry is the production of compounds of carbon and hydrogen. Many other catalysts are used in the preparation of these compounds. In fact, the periodic table includes a number of such compounds, like methylene chloride, methanesulfonyl chloride, chloroform and mixtures of hydrogen sulfide and methane. Molecules such as chlorine are also used in organic chemistry for the preparation of phenols and chlorinated hydrocarbons.Another aspect of organic chemistry is the evaluation of chemical reaction. The procedure involves testing and evaluating the reaction conditions used for the preparation of a chemical compound. The reaction may take place in the presence of one or more forms of energy (electrolysis, oxidation, etc.) Chemical reactions which involve the use of heat can also be evaluated in organic chemistry.The function of the oxidative switch is to fa cilitate the oxidation of an unstable chemical compound, in order to prepare a stable compound. It is the principle of an oxidative switch that makes oxidation to be a part of the catalytic process. Oxidation can lead to the formation of a molecule known as halogen, which is a stable compound.All the elements that can be found in nature are represented in organic chemistry. This branch of chemistry offers a wide range of products, the combinations of which are important in the production of chemicals.

What is it Like to Attend Willamette University

What is it Like to Attend Willamette University Emily earned her bachelors degree in economics from Willamette University. She specializes in algebra tutoring, economics tutoring, and a number of other subjects. Below, she shares her experience at Willamette University: Describe the campus setting and transportation options. Emily: The campus is in the heart of Salem, Oregon, which is a moderately-sized city. The campus is right across the street from the Oregon State Capitol, making it really convenient for students to have internships or even part time jobs while going to school. It is right on the edge of downtown, so there are some good restaurants. It is within walking distance of a mall as well. I didnt need a car while attending school, because everything was within walking distance and buses are available. The campus is also close to a few parks, so its good for runners and people who are active. In general, its pretty safe as long as you avoid going off campus by yourself at night. How available are the professors, academic advisers, and teaching assistants? Emily:Willamette is a small liberal arts college, so there arent any teaching assistants. Class sizes are small and, in general, the professors are incredibly helpful and highly available for students. The departments are small, so you typically get to know all of the professors really well during your four years. They also make sure that tutors are available to students. The benefit of going to a small school like Willamette is that you get to easily access your professors. How would you describe the dorm liferooms, dining options, location, socialization opportunities with other students? Emily:At Willamette, students live on campus for two years. The rooms are pretty large for dorms and the dining options are good. There are a lot of on-campus activities, which make it easy for students to meet each other. Which majors/programs are best represented and supported? Emily:I think that all of the departments are well supported. I studied economics, because that is what I was most interested in from the beginning. My professors were all really helpful and I was able to get involved in the department as a tutor during my last year in the program. 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? Emily:I thought it was incredibly easy to make friends as a freshman. Greek life at Willamette is a little different than at other schools. All of the sororities are on-campus, so women who pledge move into the house during their second year rather than staying on the main campus in the dorms. The sororities all offer their own meals as well, so you dont see their members during meal times. This was one of the things that I didnt like as a student, because I believe it created unnecessary divides in the community. I was not a part of Greek life and I feel that by not joining, I lost some friends. Fraternities are mostly off campus, so while there may be a lot of members, they still remain a part of the Willamette community. How helpful is the Career Centerand other student support services? Emily:I mostly used the career center after graduating while applying to graduate school. I think they were overall pretty helpful. I think that if youve never written a cover letter or applied for a job before, then the career center is a really good resource. How are the various study areas such aslibraries, the student union, and dorm lounges? Emily:I was a library studier. The Willamette Library is a great size, and is separated into a quiet area and a group study area. The only time the library got overly crowded was during finals week, but you could usually find a spot in the quiet section. The other great study spot on campus is the coffee shop called the Bistro. If youre someone who likes studying in a fun atmosphere with music, its a great place. In general, most students didnt study in the dorm lounges. Some classrooms also remain unlocked (you have to use your card to get into the building), so that was also a common place for students to study. Describe the surrounding town. Emily:Salem definitely isnt a city atmosphere. There are good restaurants downtown, good running areas, and good shops. There arent a lot of options for activities, but overall, I think students like what is available. How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Emily:Class sizes are amazing at Willamette. In general, Id have around 25 students in a class, but there are also many discussion-based classes that only have 8-10 students. The student body is relatively small, so its nice because you get to know everyone! Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Emily:I think my relationship with my advisor was a really great one. I met him as a prospective student (he was the department chair), I took my first economics course with him, and then he became my advisor. Our relationship was really helpful as I made decisions about my thesis, chose classes, and graduated. If you use the resources to your advantage, you can make so many great relationships with faculty and staff that will help you to succeed both in school and after graduation.

Set Up a Study Plan With Your Tutor That Works for You

Set Up a Study Plan With Your Tutor That Works for You Tutoring is an excellent way to learn more in-depth about a particular subject, whether you feel youre falling behind in class or you want to get ahead. Since tutoring is extremely adaptable, its up to you to make your study plan the most effective it can be. Here are a few tips on setting up a plan with your tutor for your best chances of success: 1. Discuss purpose and end goals Before your first tutoring session, talk about your purpose and end goals. Are you trying to catch up or enrich knowledge youve already gained? How much familiarity do you have the subject? It can be helpful to show your tutor recent projects or assessments youve had in the class including specific problems or questions youre struggling with as well as discussing your classroom instructors teaching style. You may need tutoring for an upcoming test, like a school exam, or a standardized test, like the SAT. In that case, youll want to discuss a timeline for being adequately prepared, so that he or she can plan accordingly. 2. Structure your tutoring hour A great aspect of tutoringis the complete freedom to structure it however you and your tutor would like. Discuss any learning strategies that youve found helpful in the past, such as flashcards, practice problems, or timed writing. What kind of learner are you? Do you respond better to visuals, audio, reading/writing, or physical movement? Your tutor may include activities other than your obvious strengths, but this information would also be helpful for him or her to know. Have a conversation about splitting up the actual session time into activities like instruction, independent practice, and review. You and your tutor may even decide that tutoring sessions may look different from week to week. 3. Talk about curriculum and tutoring materials Besides the actual time spent with your tutor, youll want to talk to him or her about teaching and supplementary materials that would work best for sessions. Decide how closely youd like your tutoring time to follow in-class instruction. If youd like a direct correlation to class and homework, you might provide more of the material and ensure your tutor has access (before or during sessions) to your school textbook, workbook, and homework assignments. If youd like to enrich your knowledge with outside material, talk with your tutor about finding an outside text. He or she likely knows of some, and you could also ask your teacher for recommendations. Some subjects or study plans may not even require another text; instead, your tutor may plan activities and instruction without an additional book. 4. Communicate related classroom instruction Tutoring can be an extremely effective way for you to learn concepts and skills alongside regular school work. One key to this is making sure you communicate regularly about what youre working on in class and how your classroom instructor may be teaching specific information. Your tutor will be able to use this knowledge as a foundation for what he or she will practice with you. Also, discuss the pacing of your class and any change in test dates or projects with your tutor. Decide how and in what way youll communicate outside of sessions, whether by text, email, or phone. Talking about the above things with your tutor can set up clear expectations for the both of you, so that you can get the most out of sessions as possible. Dont forget to keep lines of communication open, as your purpose and goals may shift over time. Your tutor will be grateful for this clarity, and you will also benefit from it in the long run.

Derivative Trig

Derivative Trig Derivative trig is used in finding derivative of trigonometric functions. The derivative of trig functions can be found by using definition of derivative and by using limit rules. It is a process of finding rate of change of trigonometric function with respect to a variable. Trigonometry is useful in areas such as astronomy, surviving, physics etc. Remember derivatives of basic 6 trigonometric functions. One derivative is shown in example 1. Problem 1: Find the derivative of d (sin x) / dx Solution: Given: d (sin x) / dx. = By the definition of derivative, d f(x) / dx = lim h-0 f(x + h) f(x) / h = d (sin x) / dx = lim h-0 (sin (x+ h) sin x) / h = lim h-0 (sin x cos h + sin h cos x sin x) / h (using trigonometric identity) = lim h-0 (sin x (cos h 1) + sin h cos x) / h = sin x lim h-0 (cos h 1) / h + cos x lim h-0 (sin h) / h (By separating the limits = By applying trigonometric limits we get, d (sin x) / dx = sin x. 0 + cos x. 1 = cos x Problem 2: Find the derivative of d (2sec(x) 5 cot (x))/dx Solution: Given: d (2sec(x) 5 cot(x))/dx = We know the derivative of basic 6 trigonometric functions = So, d sec (x) / dx = sec(x) tan(x) and also d cot(x)/dx = - csc^2(x) = d (2sec(x) 5 cot(x))/dx = 2 sec(x) tan(x) 5(- csc^2(x)) = 2 sec(x) tan(x) + 5 csc^2(x) = Therefore, the derivative of d (2sec(x) 5 cot (x))/dx = 2 sec(x) tan(x) + 5 csc^2(x)
