Required Texts:

NOTE: Chemistry 14CL includes topics already covered in 14A/B and 14BL. In order to understand the lectures and do well in the labs (these include prelabs / postlabs and exams), it is important for all of you to review (on your own!) all those relevant materials from Chemistry 14A/B and 14BL.

Virtual Office Hours:Chem 14CL will use the Department of Chemistry's virtual office hour function on the Internet. You may submit questions and receive answers electronically. The address is

Grading: To receive a passing grade (C-), you must complete ALL the experiments and reports and receive at least 50% of the points in the exams category.

Lab Preparation:

Post-lab Reports: Bulletin Board: Video Laboratory: Operated by the Instructional Media Library, and located in Powell 270. This facility is open daily. Videotapes for assignments on the laboratory schedules will be available for individual student viewing. You are expected to view the approporiate program for the week's experiment before your lab section meets. Recommended Text: Oxtoby, D. W. and Nachtrib, N. H. Principles of Modern Chemistry (3rd Ed) Saunders (or equivalent general chemistry text) Safety Goggles and Protective Clothing: Eye protection must be worn in all laboratories whenever any laboratory work is in progress. Recommended safety goggles may be purchased from the Undergraduate Chemistry Fraternity - AXE - Room 1275 Young Hall. Other styles of goggles are available at local bookstores.

A heavy vinyl or rubberized apron or full-length lab coat, closed-toe shoes, and long pants must be worn when doing experimental work. Aprons may be purchased from AXE or the student store. If you wear an apron, your shirt must cover your shoulders and upper arms. Shorts and sandals do not provide adequate protection for laboratory work. You will be barred from the laboratory if you are not wearing appropriate protective clothing. Latex gloves will be provided for those experiments using chemicals that are hazardous to skin.

Laboratory Notebooks: Laboratory notebooks designed for duplicate records are available from the Undergraduate Chemistry Fraternity - AXE - Young Hall 1275 and the student store. All experimental data and complete reports will be recorded in this laboratory notebook. Grading Criteria: Your mastery of the course will be measured through your performance on the exams, reports, experimental accuracy, calculations and analysis of data; and your lab technique. Qualities that will be considered in this latter category include your performance in observing safety regulations such as wearing eye and personal protection in lab, following safe lab procedures, working independently and coming to lab prepared, completing the assigned work within the scheduled laboratory periods, coming to lab on time and turning in assignments promptly, and disposing of waste in proper receptacles.

Chemistry 14CL is graded on a mastery basis. Letter grades are based on the course point total. (Please note these grades are assigned only at the end of the quarter when all items have been graded; the percentage on a portion of the course is not a meaningful measure of your total performance.) Plus and minus grades are frequently assigned, but final decisions to award these grades are not made until the end of the quarter when all the student data have been evaluated. As a rule of thumb, the course grades are assigned as follows:

90 - 100% = A
80 - 90% = B
65 - 80% = C
50 - 65% = D
0 - 50% = F
