Chemistry 150: General Chemistry

 

Course meeting times:        MW, 6:00 - 9:50 p.m.

Lectures, discussions and labs will be held in Room AS1519

 

Text: Chemistry by McMurry and Fay, 4th edition

Other required materials:

• Lab notebook, preferably the carbonless copies type

• Scientific calculator

• An e-mail address you will check a couple times per week

• Safety goggles

• 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 valence bond and molecular orbital theory, thermodynamics (enthalpy and entropy) and kinetics (reaction dynamics), mathematical descriptions of the states of matter, solutions and their properties, chemical equilibrium and the unique role of water. These topics are contained in Chapters 7–14 of the textbook; we may cover additional material if we have time at the end of the quarter.

 

Prerequisites: Math 102 (or equivalent) and Chemistry 140 (or the equivalent) are prerequisites for this course; these prerequisites are critical for your success in this class.

Homework problems: Note that all even numbered problems’ answers (as well as the answers to the problems posed within the chapter text) are in the back of the book; you are responsible for checking these answers. The grader will check more carefully the odd-numbered problems at the end of the chapter; 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.

 

In the case of problems with multiple parts, assume all parts of it are due unless specified otherwise on the list below.

 

Chapters 7 and 8 (25 points) Problems 7.22, 7.26, 7.27, 7.28, 7.30, 7.102, 7.114, 7.122, 8.3, 8.7, 8.9, 8.12, 8.17, 8.21, 8.24, 8.69, 8.93 a and b, 8.99, 8.107, 8.115

 

Chapter 9 (25 points) Problems 9.2, 9.6, 9.12, 9.16, 9.20, 9.22 (and note the percent difference), 9.23, 9.28, 9.32, 9.42 (will come in handy in a lab), 9.46, 9.52 (compare this to a typical “good” man-made vacuum of 10–6 torr), 9.60, 9.72, 9.92, 9.101 a, b and c, 9.105 a, b and c, 9.113 a and b, 9.119 a and b

Note: doing the homework problems helps you keep up with the material!

 

Labs: Safety first! You must wear goggles in lab; these are available for purchase in the bookstore (or you may bring them from home or work — they must protect the side of your face). You will store your goggles in your lab drawer.

 

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, labs and exercises cannot be made up; that's why I drop the lowest exam and exercise score.

 

Exams: The midterm exams are one hour in duration and the final is two hours. These items represent individual learning, so no collaboration or use of the textbook is allowed. However, since they assess what you learned over the course, they will be open notes, handouts, lab book, exercises and calculator.

 

Exercises: There will be (roughly) weekly exercises designed to illustrate the topics we are covering in class. The exercises are due at the next midterm. You may work alone or in groups on these, though each person in the group should keep her or his own copy for use during exams.

 

Biodiesel special project: You and up to two partners will devise an experiment using biodiesel (based on some open-ended questions), perform a bench experiment  and present a short illustrated oral presentation to the class, as well as turn in a written report. There will be a further handout on this assignment, and it will require some time outside of class.

 

Cheating: Please 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 twenty-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.
