CHEMISTRY 111 SYLLABUS

FALL 1996


To The Student:
Chemistry 111 is the general chemistry laboratory course designed to accompany Chemistry 101. It is assumed that students are concurrently enrolled in both the lecture and laboratory courses. We hope that through this laboratory course you, the students, will gain useful skills and knowledge that will complement what you will be learning in the lecture course.
In this course you will be given instructions on useful lab techniques and will gain experience in the treatment of laboratory data. Through a variety of applications many concepts of general chemistry will be illustrated. To assist you in gaining the most from this course we have, wherever possible: (1) selected exercises with a wide variety of applied chemical principles, (2) designed pre-laboratory instruction to assist you, and (3) arranged for a help desk to provide help outside of the time that you are in lab. The help desk is in Room 415 of Heldenfels Hall. Check the bulletin boards outside of Rooms 100, 401 and 413 for schedules of the help desk, etc. You may also call the First Year Chemistry Electronic Information Center at 862-3456 for information on weekly assignments, quizzes, etc.
Everyone associated with this course wants it to be enjoyable, instructive, and meaningful. Please feel free to call upon us if we can be of assistance during the semester.

The Faculty and Staff
First Year Chemistry Labs

You Will Need:
1. The laboratory manual (Measurement and Synthesis in the Chemistry Laboratory, by L. Peck and K. Irgolic).
2. The problems disk (CHEMI-SKILL-BILDR Personalized Problem-Sets in General Chemistry, disk 1, version 4.1 or later, James D. Spain).
3. The lab notebook (8 1/2" x 11", perforated alternating white and yellow pages with carbon paper).
4. The textbook used in Chemistry 101, (General Chemistry, by Whitten, Davis and Peck, 5th Edition).
5. Approved eye protection. University and Departmental Regulations require that splash-proof, chemical goggles be worn by everyone present any time any experimentation is being conducted or any time chemicals or equipment are being moved by anyone in the laboratory. (The Graduate Chemistry Fraternity will be at the labs the first week of lab to sell suitable goggles). Failure to wear goggles will result in expulsion from the laboratory for the experiment involved. You may also wish to bring a calculator, a laboratory apron, or a nonflammable lab coat. An apron or lab coat will be required if your shorts or skirt do not cover your knees.

Policy on Safety and Breakage

Before working in this laboratory course, every student must read the "Laboratory Safety" rules in the laboratory manual plus the Departmental Rules and agree in writing to abide by these rules. It is imperative for your safety that you and everyone around you strictly adhere to the Safety Rules. Failure to comply with the safety regulations (e.g., by not wearing eye protection at all times; by wearing open-toed shoes, short skirts or shorts; by running an unauthorized experiment; or by removing chemicals or equipment from the lab) may result in dismissal from the course or deduction of points on your reports.
In this course you will be utilizing equipment furnished by the Chemistry Department. It is your responsibility to properly maintain the equipment while it is in your care. If equipment that has been entrusted to you is not returned in satisfactory condition, you will be held responsible for it.

Grading and Absence Policy

Absences:
The attached schedule gives the date that each experiment is to be completed. Make-up sessions are scheduled for those students who have missed prior experiments due to university approved reasons. Excused absences must be reported to your instructor in a timely manner.

Data Sheets: A data sheet must be submitted at the end of the lab period to receive a grade for that day's experiment. The data sheet may not be graded in some sections; however, the Report Form for the corresponding experiment will not be graded if the data sheet is not submitted the day the experiment is conducted.

Reports: For each experiment you will receive a total score between 10 and 0. The Report Form is due the same day that the experiment is performed unless indicated otherwise. The Report Form must reflect information obtained by you while in the laboratory and recorded on your data sheets. The Prelab Exercises associated with each experiment are due before you start the experiment. Neatness and completeness of your data sheets and prelab exercises may be considered when points for organization of data, etc., are assigned as a part of your Report Form grade. Many instructors deduct up to 4 points from the Report Form for incomplete data sheets and/or 4 points for incomplete or messy Prelab Exercises. Points will be deducted for Report Forms not submitted on the date indicated. Reports more than two weeks late will not be graded.

Quizzes: Quizzes (16 points each, usually 3 or 4 points per question) are scheduled at various times during the semester. The quizzes will reflect what you should have gained from previous weeks' experiments, what you should master before beginning the current week's experiment, your understanding of the exercises on the assigned CSB programs and your ability to utilize techniques and concepts.

Grades: At the end of the semester the scores on all quizzes, reports, Chemi-Skill-Bildr scores (4 pts if 90-100%, 3 pts if 80-89%, 2 pts if 70-79%, and 0 pts<70%) and written (30 points) and practical (10 points) finals will be totaled for each student and the final letter grades for the course will be determined based upon the ranking of each student's total points compared to other students in that section. For the past several semesters the average grade in every section has been a mid-B. We do not expect the grade distribution to differ this semester. In the past a few sections have had averages of over 90% that were still B's while in other sections the A's have been as low as 82%.

You must take the final exam to obtain a final course grade of D or higher. However, taking the final exam does not insure one a grade of D or higher.

Dishonesty: Students are expected to be the sole source for any work submitted in their name or the name of a group designated by the instructor. The utilization or submission of work of other students, tutors, or other agents not authorized by the instructor is a violation of scholastic dishonesty policies and disciplinary steps will be taken. Only authorized electronic or printed materials or equipment may be used in or near the laboratory. Unauthorized programs, materials, or equipment will be confiscated or destroyed.
No TOAD! (Ask me, your instructor, the meaning of "no TOAD").

You should have already started to work on Programs 1, 2, & 4 (all parts) of your Chemi-Skill-Bildr (CSB) disk. Although we will often not collect the results of your work with the CSB disk nor test you on it until later, if topics are covered in lecture before they are assigned in this course, we encourage you to work those units on your CSB disk at about the same time that the same topics are being discussed in lecture. The first quiz in this laboratory course, the week of 9/30-10/4, will test you on the observations of the experiments assigned prior to that time, the calculations and equations associated with those experiments, safety rules and regulations and Units 1, 2, and 4 (all parts) of the CSB disk.
