CHEMISTRY 116 - FALL, 2004 COURSE INFORMATION HONORS GENERAL COLLEGE CHEMISTRY I Professor Richard Burns (5405 SES, x6-8703) E Mail: rpburns@uic.edu Office Hours 3:00-4:00 MWF Lecture: 12:00-12:50 MWF, 140 BSB 1 Required: Oxtoby, Gillis & Nachtrieb Principles of Modern Chemistry 5e, Thomson Learning, 2002. Freeman Student Solutions Manual for above Chemistry 112/116 Laboratory Manual Laboratory Notebook Splash goggles (not just standard eyeware) are required in all laboratories. All required items are on sale in the UIC Bookstore. COURSE REQUIREMENTS Prerequisites: Students may register for Chemistry 116 after qualifying by a placement test score or by taking Chemistry 101, Preparatory Chemistry. Proficiency in math at the level of precalculus is assumed. If you do not satisfy the prerequisites, you will be dropped from the course. Registration: Students must be registered for the course and also the proper lab / discussion section. The Department does not allow students to work in a laboratory section unless they are registered for the course including that particular section. In particular, the Department does not allow students to register for one laboratory section and do their work in a different section, except as a part of a regulated make-up policy. Teaching Assistants to not have the authority to waive this rule. Last day to Drop: The deadline is Friday, October 1, 2004.. COURSE COMPONENTS Lecture: There are three lecture periods each week in the course. While attendance will not be taken, you should attend them and take good notes. The final answer to the question What will be on the exam? can only be had by diligent attendance at the lectures. It may be announced that certain material will be omitted or added to the original lecture material. Exams: There will be three midterm exams. Each exam will be worth 110 points and will take 50 minutes. They will be held during the regular class periods. Attendance at the final exam is mandatory and is tentatively scheduled for Friday, December 10, from 8:00-10:00. It will be cumulative; will be worth 300 points; and 20% to 33% will concern lab material. No makeup exams will be given. Grading: The contributions to the final grade total will be in the form: THREE MIDTERM EXAMS 330 points FINAL EXAM 300 points LABORATORY 150 points RECITATION 120 points HOMEWORK 100 points TOTAL 1000 points
NOTE: Regardless of your work in the rest of the course, you must get at least 315 points on the midterms and the final and complete and turn in at least 12 lab reports to receive a passing grade 2 Discussion section. The weekly discussion/quiz/recitation section is as important as the lecture as an opportunity to learn. Indeed, because of the smaller size of the discussion section, many will find it indispensable in efforts to learn and study. The class period will include a review of relevant topics in the course and an opportunity for students to ask questions of their teaching assistant. Your attendance is required at the weekly discussion/quiz/recitation, section. Tlhree 40 point quizzes will be given in the discussion section during the semester for a total of 120 points. Homework: Homework will be assigned for every lecture. Homework will be worth 100 points. Be sure to keep a copy of your homework notes for your use. Laboratory: There are fourteen laboratory experiments scheduled. Each is worth 10 points, for a total of 140 points toward the final grade. An additional 10 points will be awarded for good lab practice. Good lab practice includes attendance, lab reports, notebook, and the quality of your work in lab. You must attend the laboratory on a regular basis. There are no makeup labs. To pass this course you must complete a minimum of twelve labs and turn in twelve lab reports at the assigned times. Please pay particular attention to the following points for all labs: 1. Requirements for keeping a lab notebook Bound notebook with carbon copy duplicate pages (UIC Bookstore) Numbered pages Record data and observations in the experimental data section during the lab. All numerical data recorded in the lab notebook must indicate origin of measurement, units. Use proper significant figures All writing must be in ink (ballpoint pen) Cross-outs should be single strike-through plus initials, date and reason for cross-out. Some reasons are: calculation error, correction, misread buret etc. Sign name and date at bottom of each page Mark unused pages or parts of unused pages with an X. Initial and date Record data directly in notebook. No scratch paper is allowed. Your lab notebook must be prepared in advance of lab and will be checked by your TA before work can begin. Notebook preparation will include but may not be limited to: 1 Title 2 Objectives 3 Methodology reference 4 Balanced chemical equation if lab deals with a chemical change 5 A table of chemicals to be used in the experiment showing: Chemical Name Molecular wt. Melting point Boiling point (Use the Chemical Rubber Handbook for this information) 6 Experimental data This will consist of the title Experimental Data. After your TA has been checked by your TA, you will record data and observations in this section during the lab. All numerical data recorded in the lab notebook must indicate origin of measurement, units, significant figures
3 2. Except when we tell you otherwise, you must have the TA initial your notebook before you leave the lab. On occasion, we may ask you to turn in the carbons of your work before you leave. In addition, we may ask you to put some data in a computer program for group analysis. 3. For most labs you will be asked to write a report, following guidelines in the syllabus. This work must be your own, using data collected in the lab. If your data are wildly different from what you think you should have, then you should provide an explanation in your report. 4. YOU MUST ALWAYS WEAR CHEMICAL SPLASH GLASSES OR GOGGLES IN THE LAB. This is the law of the state of Illinois. It also complies with any standard for common sense. LABORATORY CHEMICALS AND APPARATUS ARE ESPECIALLY HAZARDOUS TO YOUR EYES, WHICH CAN BE DESTROYED IN SECONDS. If you are caught without proper eye protection, you will be removed from the lab. If this occurs more than once in a period, you will be given a zero for the lab. Do not wear contact lenses in the laboratory, even with splash goggles. Contact lenses prevent rinsing chemical splashes from the eye. Vapors in the laboratory (HCl for example) sissolve in the liquids covering the eye and concentrate behind the lenses. Soft contact lenses are especially bad because chemicals can dissolve in the lenses themselves and are released over time. Format for Lab Reports: A complete lab report might be approximately three pages in length, plus data sheets and graphs etc. Each Lab Report will have a value of 10 Points. The lab report should be typed and should include: Introduction: A one sentence statement of the nature of the experiment, including the usefulness or importance of the results. Procedure: This will ideally be a one or two paragraph description of what was done with a typical sample in the experiment. Several samples may be examined in a given experiment, but usually the same procedure will be used with all. Do not forget to include all of the balanced chemical equations used in the experiment (if any). Results: The numerical results that were obtained should be listed. The best form for this is in the form of a neat table with columns and rows clearly labeled. For some experiments, more than one table may be required. As an example, for one possible experiment, one table might be needed for a calibration, and one table for the analysis of an unknown sample. Sample Calculation(s): A neat and detailed presentation of the way a representative set of the data were used to calculate the results should be shown. Conclusions: The meaning of the results should be presented clearly. The 10 points will usually be allocated as follows: Pre-Lab 1.5 points Introduceion 1.0 points Procedure 0.5 points Experimental data 1.5 points Calculations and Results 2.5 points Discussion of results and their accuracy 2.5 points Conclusions 0.5 points Total 10.0 points
4 Missed assignments: We recognize that some students may miss some assignments because of illness or similarly serious reasons. If this happens, you should bring ample documentation (e.g., a note from a doctor) to Prof. Burns or your teaching assistant as soon as possible. We will verify the excuse in many cases. If you present a justifiable reason for missed work, the grade for that item will be made up by averaging other grades in that component of the course over the whole semester. Academic Dishonesty: Academic dishonesty in all forms will not be tolerated in this course. Any student caught cheating will be immediately assigned a grade of E by me. Further disciplinary action will then be discussed with the department office and the Dean. If you are considering cheating, please remember that the few points, or even few dozen points, you receive if you succeed cannot match the failing grade you receive if you are caught. GENERAL CHEMISTRY HELP CENTER (ROOM 201 SES) Room 201 SES is designated as a study and help center for general chemistry students. It opens on the first day of the second week of classes. You may come here to study on your own or with other students. In addition, teaching assistants are usually available, throughout the week, to help you. Also in the help center are a set of microcomputers with useful software. These are there for your use for study or to help prepare data for your lab reports.
