We will be covering chapters 13-17, 19, 20, 24. There will be some topics in the textbook that will not be covered in lecture. You will not be tested on this material unless I have specifically assigned it for you to read. There will also be a few topics that are not in the book that I will cover in lecture. You are responsible for this material.
The importance of understanding each topic in the course cannot be overemphasized. Chemistry is truly a course that relies on understanding early topics, including those of 1411, before an understanding of later topics can be realized. Since General Chemistry is partially a skills course, there will be quite a few problems to work. It is required that you purchase a scientific, non-programmable calculator.
If you are having difficulty with a particular topic, be certain to get individual help promptly. There are also tutors in the ELC to help, and each division has two counselors to help. The counselor assigned to the sciences is:
Ms. Sue Jan Herber

SEMESTER / LOCATION / TIME / CALENDAR
ATTENDANCE EXPECTATIONS
Studies have shown that consistently missing class and/or being tardy to class has an adverse effect on student performance and success. Any student tardy to lab will not be allowed to perform that lab. Laboratory instructions are crucial, not only to understanding the experiment, but for safety purposes as well.
NO LONGER ATTENDING CLASS DOES NOT CONSTITUTE WITHDRAWAL FROM THIS CLASS, NOR DOES A STUDENT’S NOTIFICATION TO THE INSTRUCTOR THAT THE STUDENT WISHES TO BE DROPPED. FAILURE OF A STUDENT TO FILL OUT A “SCHEDULE CHANGE FORM” TO OFFICIALLY DROP THIS CLASS MAY RESULT IN A GRADE OF “F.”
ANY STUDENT WHO MISSES THE FIRST WEEK OF CLASS MUST DROP.
EVALUATION
The breakdown of points is as follows:
45% Tests
5 % Group Work and Quizzes
30% Laboratory Assignments & Exams
20% Final Exam
Problem Sets (see below)
The test grade will be calculated from the average of the top four out of five tests. The score from the fifth test will be dropped. No make-up exams will be given. If you believe an error was made in error in grading the test, you can ask for a regrade. Tests must be written in unerasable pen to be eligible for a regrade. Missing the final exam will drop your grade by one letter.
Note that the laboratory grade is thirty percent of the course grade. In other words, it has a very significant impact on your final grade. The lab grade will be earned by completion of lab assignments, pre-labs, lab quizzes and a lab notebook. The lowest lab grade will be dropped when the average is determined.
There will be five problem sets given to coincide with the material presented in lecture in order to help prepare for the tests. You may consult fellow students as well as the instructor for help with the problem sets, but you may not simply copy answers. The problem sets will be given a grade of check+, check, or check-. Each check+ will add half a point to the final grade, and each check- will subtract half a point from the final grade. Each set not turned in will subtract one point. The problem sets will be due the Wednesday before a test, unless otherwise specified.
The letter grades will be determined from the calculated numerical grade based on a class curve. I will therefore not be able to give more than an approximation of your letter grade during the semester. However, a 90 average guarantees an A, an 80 average guarantees at least a B, a 70 average guarantees at least a C, and a 60 average guarantees at least a D.
GROUP WORK
Students will be assigned to small groups of 3 to 4 students. The members of each group are chosen by the instructor. You are encouraged to work in your group during class and thus will be required to sit with your group in class. (The members of your study groups will also constitute your lab partners.) Several “group problems” will be assigned to groups for each chapter or testing unit. Although not inclusive of all material covered, these questions will be a good cross section. After the completion of each testing unit, thirty minutes of class time will be devoted to the working of group problems. Because thirty minutes will not be sufficient time to work all problems, students are encouraged to work in their group outside of class.
After group problems are reviewed, a short in-class quiz will be given, individually, consisting of one or more group problems. These quizzes will count 5% of your total grade. However, one member of each group, chosen randomly, will be selected to solve one or more of these questions and then explain those problems in front of the class using his/her notes only. The chosen student’s thoroughness and accuracy of explanation will determine his/her 5%. In addition, a grade of 0 to 3 will be assigned to each member of that student’s group depending on whether the answer and explanation are complete and correct. These points will be counted as EXTRA CREDIT on the appropriate test.
Group board work is considered a review. Obviously, if a group member is not present for the board work, he/she cannot receive his/her group points. It is your responsibility to be present at that time.
If a group becomes smaller than three members, the instructor will probably consolidate that group with another group.
LABORATORY SAFETY
Lab safety will be stressed in this class. Safety goggles must be worn at all times during the lab period. You will not be admitted to lab without proper eye protection. Additionally, a student may be dismissed from lab if he/she removes his/her safety glasses during the lab. Certain chemicals you will be working with may present a health hazard, be extremely reactive or flammable. The instructor will review all safety aspects at the start of each lab. Plan to wear close-toe shoes in the lab and avoid using flame sources, such as Bunsen burners, if you wear synthetic nails.
LAB GUIDELINES
In general, a pre-lab exercise must be completed before each laboratory. Normally the pre-lab assignment consists of reading the experiment and any supplemental material pertaining to the experiment. Additionally, the laboratory notebook must be prepared according to the guidelines given below. If the student has not completed the required pre-lab assignment by the beginning of the laboratory period, he/she will not be allowed to participate in the laboratory.
The grade for missed lab activities is zero. Missed labs cannot be made-up. Since the lowest lab grade is dropped, a single missed lab will not adversely affect the final grade.
Lab reports are usually required for each laboratory experiment. Lab reports consist of both the lab modules themselves with completed data tables and answers to all questions, unless notified otherwise. A lab quiz will be given on the day that the lab report is due, which will generally be a week after completion of the lab.
The grade for a lab is based on three factors: 20 percent for completing the pre-lab and signature verifying that the data was recorded in the lab book, 40 percent for the lab report, and 40 percent for the quiz over that lab. To encourage good lab technique, the quality of your data will be a part of the lab report grade.
If you have missed a lab, you may still take the lab quiz, although you will obviously not earn the points for the lab assignment. Conversely, if you complete the lab but are not in class for the lab quiz, you will lose those 40 points. Note: The lab quiz will be given at the beginning of class in a limited amount of time. If you are late to class, you may not have time to complete your quiz, thereby losing points.
Guidelines for laboratory notebooks:
1. The lab notebook will be a bound notebook.
2. The lab notebook will have a table of contents listing the page numbers of each lab. Each page of the notebook following the table of contents will be numbered consecutively. No pages should be ripped out of the notebook under any circumstances. Write only on one side of the page.
3. All information in the lab notebook will be in ink. Corrections will be crossed out with a single line through the incorrect statement or data. There should be no erasures or white-out. Laboratory notebooks are considered legal documents in academic and industrial research.
4. Each lab report will be organized as follows:
a. Title of the experiment.*
b. Date that the experiment was conducted*
c. Purpose of the experiment.*
d. Safety hazards*
e. A step-by-step procedure of the experiment*
f . A quantitative record of the actual data obtained in the experiment
*Pre-lab (to be completed before class)
5. The notebook will be ready for evaluation by the instructor at the beginning of the class period with a completed pre-lab write up (a – e above) and will be signed by the instructor to indicate completion. The student will not be permitted to do the lab exercise if the pre-lab write up in his/her notebook is not complete.
6. Each student must record his/her own data in his/her own lab notebook, not in the laboratory textbook or module. When a student has completed the lab, the instructor will sign his/her completed data record. This indicates that not only has the lab been completed, but that the student has left his/her lab area clean and all equipment has been returned to its proper place. All data should be recorded in the lab notebook, not in the laboratory textbook or handout.
