Chemistry 11. General Chemistry I: Properties and Structure

DESCRIPTION: This is the first of two courses in general chemistry (the second is Chemistry 13). In Chemistry 11, we first review the fundamental vocabulary and stoichiometric relationships in chemistry. We then study additional mathematical and physical tools used to describe chemical reactions in solution and in the gas phase. Next, we consider in detail the properties of atoms and the chemical elements. We then develop classical and quantum mechanical models of the structure of molecules, especially organic compounds. We conclude with the properties and interconversions of states of matter, and oxidation-reduction reactions.

Students who have done well on the chemistry placement exam should consider taking Chemistry 13 this fall. Please talk with the Chemistry 13 instructor, Prof. Wolsey, for advice. Remember that the deadline for adding classes is Friday, September 22.

Doing experiments is a critical part of learning chemistry, and you are required to be registered in one of the four weekly sections (all of which meet in Olin-Rice 343):

Section	Day	Time	Instructor
11L02	Tuesday	8:30 – 11:40 a.m.	Sharpe
11L04	Tuesday	1:00 – 4:15 p.m.	McCormick
11L06	Thursday	8:30 – 11:40 a.m.	Parson
11L08	Thursday	1:00 – 4:15 p.m.	Varberg

Lab attendance every week is mandatory. If very special circumstances preclude your attendance at a session, you must notify your instructor beforehand and make arrangements to make that session up.

LECTURES: MWF from 10:50 a.m. to 11:50 a.m. in Olin-Rice 350. Attendance is not mandatory, but highly encouraged. It may even prove entertaining from time to time.

INSTRUCTOR: Prof. Keith T. Kuwata, Olin-Rice 318, 696-6768, kuwata@macalester.edu.

REQUIRED TEXTS: (Lecture) Jean B. Umland and Jon M. Bellama, General Chemistry, 3rd ed., Brooks/Cole, 1999. (Lab) Emil J. Slowinski, Wayne C. Wolsey, and William L. Masterton, Chemical Principles in the Laboratory, 7th ed., Harcourt, 2001.

OTHER REQUIRED MATERIALS: Macalester College and the State of Minnesota both require that you wear safety goggles during all laboratory sessions. You may purchase a pair at the Ruminator. You should also own a scientific calculator; however, programmable calculators are not allowed during exams.

PROBLEM SETS: You will be required to turn in solutions to the problems at the end of each chapter (of Umland/Bellama) assigned on the course schedule on the indicated due date. No late homework will be accepted unless you are sick, and must, in any case, be turned in before the exam on that chapter. However, the problem set immediately before each exam will not be collected.

For mathematical problems, you must show the process by which you obtained your answer. This final numerical answer must contain the correct number of significant figures and have the appropriate physical units attached. This is required to receive full credit on both homework and exam problems.

Doing the assigned homework is essential for you to learn the material and do well on exams. I will post solutions to problem sets after they are due, and you are encouraged to read them and discuss them with me. You are also encouraged to work with other people, but what you turn in must be your own work. You may also want to do extra problems whose answers are in the back of the book (blue) or on the web (red): http://www.brookscole.com/chemistry/umland_gen_chem/chapter/home.html

EXAMINATIONS: There will be four fifty-five minute examinations during the normal lecture time slot, as well as a two-hour final examination on Monday, December 18, 10:30 a.m.-12:30 p.m. (make your travel plans accordingly!) A legitimate reason (e.g., verified serious illness) for missing a midterm must be discussed with the instructor prior to the exam. All exams will be closed-everything. Any information you are not required to have memorized will be provided in your exam booklet. You will need to bring your own non-programmable calculator to exams. Other calculators will be confiscated, and you will not be provided with a substitute. Pagers, cellular phones, laptop computers, and other such electronic devices, are also not allowed in the exam room.

GETTING HELP: I will be available in my office M 4:40-5:40 p.m., W 2:20-3:20 p.m. and F 2:20-3:20 p.m. If you can’t make one of these office hours, please make an appointment with me. An excellent resource is Darlane Kroening (OR314, x6224) and her student tutors at the Macalester Learning Center in the Lampert Building (close to the NE corner of Grand and Snelling). The Chemistry Department also provides student tutors. We are all eager to help you do well in Chemistry 11!

GRADING:

Homework: 10%

Each Hour Exam: 10%

Lab Work:30%

Final: 20%

Grades will be assigned based on your cumulative percentage of points. The following minimum scale is guaranteed (specific thresholds for + and - will be set at the end of the term):

90%-100% A 80%-89% B 70%-79% C 60%-69% D

Midterm grades will be based on this scale. One or more of these grading thresholds may be adjusted downward at the end of the term at my discretion.

ACADEMIC INTEGRITY: Obtaining copies of exams prior to their administration, using another person to take exams for you, using unauthorized materials during exams, sharing or stealing information during an exam, and alteration of a graded exam and then requesting a regrade all constitute cheating and are forbidden. As per the Macalester Student Handbook, I will report any clear violation of academic integrity standards to Ellen Guyer, the Dean of Academic Programs
