Pang ([email protected]) Office Hours: Tuesday 10-11 and Thursday 10-11 in 2070A Young Hall Laboratory Room(s): 1370 & 1379 Young Hall Enforced Requisites: Courses 20A (C- or better) and 20B (either concurrent enrollment or C- or better) Virtual Office Hours: Chemistry 20L will use the Department of Chemistry's Virtual Office Hour (VOH) for posting report guidelines and office hours on the Internet. The address is http://voh.chem.ucla.edu/. Course Web Site: Go to the course VOH page and you will find a link to the class Web site. Section Instructor: Teaching Assistant. Times and locations of all TA office hours will be posted on VOH by the end of the second week of the quarter. You are encouraged to attend office hours scheduled by any of the TAs. Lecture Schedule: 9/28 Introduction, Measurements and Errors 11/2 Chemical Kinetics 10/5 Theory on Beer's Law and Concentration Units 11/9 Theory on Distillation & GC 10/12 Introduction to Acids and Bases 11/16 Acid Base Equilibrium (I) 10/19 Phosphate in Detergent 11/30 Acid Base Equilibrium (II) 10/26 Midterm Exam (No Make Up Exam) 12/7 Final Exam (No Make Up Exam) Lab Preparation: You must be prepared for the experiment before you come to lab if you wish to complete the experiment in the time allotted. The course is impacted; there is neither make-up time in the course nor space for you to work in other sections. If you miss a lab, you MUST discuss the issue with the course instructor to see what other options you may have to complete the experiment. You must do your lab work in your scheduled period. In preparation for the lab, you should first study the pertinent sections in the text, review the lecture notes pertaining to the experiment, then view (and possibly review) the appropriate videos (refer to lab schedule for on-line access of the videos) for any new techniques to be used in the experiment. If a pre-lab report is required for the experiment, you MUST turn in the pre-lab report to your TA at the beginning of the lab period. Refer to the VOH for the specific report guidelines. During the lab period, you will complete the data tables and record any other observations about the experiment. A copy of the in-lab data must be turned in to the T.A. at the end of the lab period. Late pre-lab work will count as ZERO. NOTE: Technique videos can be viewed on the Internet (refer to the lab schedule for Web address). Post-lab Reports: The remainder of the lab report, - the data analysis, error analysis, and conclusions - is to be completed in the lab notebook after the experiment is completed (check VOH for guidelines). The post-lab report must be turned in to the T.A. at the start of the lab period listed under “Due Date” on your lab schedule. Unexcused late post-lab reports will accrue a penalty of FIVE percent of the grade PER DAY. No reports will be accepted after 5:00 p.m. on the last day of instruction. Required Text: Chemistry Experiments for Physical Science and Engineering Majors, 2nd Ed, Russell and Henary Recommended Text: Principles of Modern Chemistry 5th Ed, Oxtoby, Gillis and Nachtrieb, , Thomson Learning Inc. or Chemical Principles 5th Edition, Zumdahl, Houghton Mifflin Safety Goggles (OSHA APPROVED) 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. A full-length lab coat, closed-toe shoes, and long pants must be worn when doing experimental work. Lab coat can be purchased from AXE. Shorts and sandals are NOT allowed in the laboratory. You will be dismissed from the laboratory if you are not wearing appropriate protective clothing. Latex gloves will be provided in the laboratory if needed.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: (To receive a passing grade (C-), you must complete all the experiments and reports and receive at least 50% of the points in EACH category). No student can pass the course without taking the final exam. Exam(s) must be taken during the lecture section in which you are officially enrolled. Any missing exam will count as ZERO. There is NO MAKE UP for missing exam regardless of reasons.

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. Letter grades are based on the course point
