And Thur. 8:00-10:50 AM I.A. TBA S.I. Leader: TBA CHEM 101 and 102 are the first-year chemistry sequence in the core curriculum. These are 3-credit courses. All lecture sections strive to cover common content. The lecture component of Chemistry 101 covers stoichiometry, atomic and molecular structure, inorganic and organic nomenclature and structure, chemical bonding, fundamental acid/base chemistry, solution chemistry, properties of liquids and solids, and the gas laws. Additionally, it is the goal of my lecture section to help you develop the skill set to successfully complete your undergraduate degree and as most in this class are pre-something to prepare you for your professional school entrance exam.

3. Top Ten Most Repeated Comments 8a. Well organized notes with the problems available online. 8b. (Wish the material was available so I did not have to write down the problems.) 3. Tell us what to know and don’t expect us to figure it out on our own. Teach how to do the problems in class not just theory. Actually work through the problems, rather than say the rest is math. 5. I felt like I was seeing much of the material for the first time on the tests. The instructor should relate class to exams to encourage attendance. 9. His teaching methods make it easy to learn. 10. He needs to take a class in teaching. 1. But I did not have to study in High School. 6. The information covered did not pertain to my major as much as BIMS or others. 4. Used material from tests earlier in the semester on later exams. The Free Response was very random and not at all like the problems worked in class. The material in class was simpler than the material on the exam. 2. The instructor places too much responsibility on the student by not requiring homework which I feel would have helped me if I had done it promptly. Give a few quizzes to make sure we are doing the required work outside of class 7. Very good at concentrating on important material and concepts and explaining them, while spending little time on extraneous issues.

9. Problem - A situation that presents difficulty, uncertainty, or perplexity: The mere formulation of a problem is far more often essential than its solution, which may be merely a matter of mathematical or experimental skill. To raise new questions, new possibilities, to regard old problems from a new angle requires creative imagination and marks real advances in science. Albert Einstein Question - A request for data: inquiry, interrogation, query. Answer - A spoken or written reply, as to a question. Solution - Something worked out to explain, resolve, or provide a method for dealing with and settling a problem.

12. Use of Numbers Addition & Subtraction ruleAddition & Subtraction rule More subtle than the multiplication rule Answer contains smallest decimal place of the addends. When a 5 appears. Is there anything to the right of the 5 greater than zero? Is the number to the left of the 5 odd? Is the number to the left of the 5 even? (Treat 0 as even.)

Law of Conservation of Energy – A law that states that in any system not involving nuclear reactions or velocities approaching the velocity of light, energy cannot be created or destroyed. The First Law of Thermodynamics.Law of Conservation of Energy – A law that states that in any system not involving nuclear reactions or velocities approaching the velocity of light, energy cannot be created or destroyed. The First Law of Thermodynamics. Law of Conservation of Mass – Energy - Einstein’s Relativity - E=mc 2 – The special theory of relativity, which has been verified by experiment, has shown that the mass of a body changes as the energy possessed by the body changes. Such changes in mass are too small to be detected except in subatomic phenomena. Matter may be created by the materialization of a photon into an electron-positron pair; or it may be destroyed, by the annihilation of this pair of elementary particles to produce a pair of photons.Law of Conservation of Mass – Energy - Einstein’s Relativity - E=mc 2 – The special theory of relativity, which has been verified by experiment, has shown that the mass of a body changes as the energy possessed by the body changes.

Law of Multiple Proportions – When two elements combine to form more than one compound, the mass of element A which combines in the first compound with a given amount of element B has a simple whole number ratio with the mass of element A which combines in the second compound with the same given mass of element B.Law of Multiple Proportions – When two elements combine to form more than one compound, the mass of element A which combines in the first compound with a given amount of element B has a simple whole number ratio with the mass of element A which combines in the second compound with the same given mass of element B.
