Course meeting times: MTWTh, 10:00 - 11:50 a.m.

Lectures, discussions and labs will be held in Room AS1519

Text: Chemistry by Zumdahl, 5th edition

Other required materials:

• Lab notebook, preferably the carbonless copies type

• Scientific calculator

• Lab coat or apron (optional)

Purpose: This course is the second quarter of a three quarter general chemistry sequence. This quarter we will cover topics such as quantum theory; atomic and molecular orbitals, the shapes of molecules, various forms of spectroscopy, material and colligative properties, and chemical kinetics and equilibrium. These topics are contained in Chapters 7-13 of the textbook; we may cover additional material if we have time at the end of the quarter.

Prerequisites: Chemistry 140 (or the equivalent) is a prerequisite for this course; this prerequisites are critical for your success in this class.

Homework problems: Note that all odd numbered problems’ answers are in the back of the book; you are responsible for checking these answers. The grader will check more carefully the even-numbered problems; be clear in how you derived the answers! Please use only one side of the sheet of paper and box your final answers; neatly staple answer sheets together. Homework problems for the chapter are due on the same day as the corresponding quiz or midterm for that chapter. Though I encourage collaboration between students (especially study groups) to work together on these problems, I ask that each person turn in their own set of homework answers.

Questions require essay-type answers; exercises require number-crunching or short answers.

Labs: Safety first! You must wear goggles in lab; these will be provided free of charge, though if you have some that are comfortable, bring them and we will determine suitability for lab.

Lab book: Your experimental data should be recorded in the lab book. The format of the first page of each experiment in your lab book will consist of your name, your partner(s)’s name(s), the date, the experiment title, a sentence or two describing the purpose of the lab, a list of materials to be used in the lab and a drawing of the experimental setup. Subsequent pages’ format will be described in each lab handout. There may be a short pre-lab quiz concerning the lab prior to the lab period to assess readiness. You will turn in either the carbonless copy of the lab or a photocopy of the appropriate lab pages. You may also be asked to write an abstract of the lab.

Make-ups: Missed exams, quizzes, labs and exercises cannot be made up; that's why I drop the lowest quiz, exercise and homework score.

Exams: The midterm exams are one hour; the quizzes are a half-hour and the final is two hours. These items represent individual learning, so no collaboration or use of the textbook is allowed. However, since they represent learning, they will be (unless otherwise specified) open notes, handouts, lab book, exercises and calculator.

Exercises: These are given out in class as hands-on or pencil type activities. You are encouraged to work in pairs or threes. Though each group need only turn in one copy of the exercise for grading (don’t forget to write in everyone’s name), each person should have a copy of the exercise for use during exams. No sharing of exercises during an exam! An exercise is due the meeting after we go over the answers as a class.

Cheating: Don't. I will use the policy outlined in the Student Conduct section of the Student Handbook. Remember, a group project is the result of a roughly equal sharing of ideas from each member of the group. Collaboration is absolutely essential. An individual project or quiz or exam, however, is an evaluation of what each individual understands. Please do not collaborate on these endeavors.

Attendance: I will not take attendance during the quarter, but, since we meet only forty-two times during the quarter, it is imperative that you come to each meeting. Please call me (528-4509) or e-mail me (tfurutani@sccd.ctc.edu) if you are going to miss class, so that we can discuss what you have missed.

Chemical sensitivities: Due to the increasing numbers of individuals developing chemical sensitivities and the increasing awareness of such conditions, everyone who attends this class is asked to refrain from wearing any fragrance or perfume. The greatest feasible efforts will also be taken to ensure a fresh air environment free of not only the above-mentioned fragrances but also potentially harmful substances such as carbon monoxide, formaldehyde, carpet odor, organic solvents, etc. Individuals who are unsure of the importance of this policy should see the Associate Dean for additional information.
