General:

This is an introductory course in the principles of general chemistry. Contemporary topics in chemistry as well as basic chemical principles will be the focus of this course. C101 is intended for students with little or no previous background in chemistry or need a review of basic chemical principles. However, I will assume that all students have a familiarity basic arithmetic and the use of a calculator. The text for the course will be:

Introductory Chemistry: General, Organic and Biological Chemistry,

Denniston; (4th edition)

Student Solution Manual/Study Guide

Class Attendance and Decorum:

It is important for you to attend the lectures. Many concepts and ideas that are not readily found in the book are discussed during class. Do not hesitate to ask questions during lecture.

Homework:

Homework will be the odd numbered problems at the end of each chapter. Some additional problems during lecture may be assigned. Homework will be collected during the discussion section after we finish the chapter. No late homework will be accepted. All homework assignments must be submitted in the following manner for credit:

1) Name, chapter number and class (i.e., C101) clearly labeled in upper right hand of first page.

2) All problems will be worked out and numbered in sequential order.

3) All pages will be stapled.

4) Homework will be turned in on time.

Discussion:

The discussion section will be primarily used to go over class and homework material. Quizzes may be given. Students should come to these sessions prepared with questions that are derived from a serious attempt to understand these materials. It does little good for me to work out a problem for a student who has not previously attempted the problem. Such a student will not understand the significance of the solution.

Chemistry Homepage:

There exists a homepage for the chemistry department (www.iun.edu/~cpa) and a webpage for C101 (www.iun.edu/~cpanhd/deleon.html) . This homepage may contain the following features: class material: homework assignments, notices, sample exams etc.. The class should become familiar with the homepage and frequently check it as it will be used to relay messages during non class hours.

Office hours:

I am in my office a high percentage of the time. It is not hard to find me. If you have any questions about the course come by and ask. You can even come to my office outside office hours, although I prefer you see me during office hours.

Grades:

The grade for the course will be determined by the usual factors: exams, homework and the final. We will have four exams and a final. The best three of the four exams will be used towards the course grade. This policy means that a student can only miss one exam. Do not ask me if you can take a "make-up". The course grade will be determined in the following way: first the “gross course grade” will be determined by the following formula:

Gross Course Grade (GCG) = (E1+E2+E3+HW+D+2xFinal)/7

where E1, E2 and E3 are the three exam grades, D is the discussion grade, HW is the overall homework grade and Final is the grade on the final. As an example suppose at the end of the semester John Jones receives exam grades (A,B,C+,B-),Homework grade = A-, Discussion Grade = B, final exam grade = B+. The C+ exam grade will be tossed out. The following number system is used for the grades: A+=12, A=11, A-=10, …, D- = 1, F=0). Thus, JJ will have the following GCG = (11+8+7+10+8+2x9)/7 = 8.86. A GCG = 8.86 is closer to 9 than to 8 and thus JJ’s GCG is a B+.

The net course grade (the actual grade you receive) will differ slightly from the GCG by subjective factors such as improvement throughout the semester, willingness to contribute to the class, overall effort etc. These factors come into play when a student is near the border between grades. For example had JJ’s GCG above been near 8.5 these subjective factors would come into play to determine whether JJ receives a B or B+ for the course.

Withdraw, Incomplete Policy: Withdrawing from the course must be done in a timely fashion according to the university's withdraw policy. I cannot grant a withdraw if the withdraw deadline has passed. A grade of incomplete (I) can only be given under the following conditions (all of which must be met):

1) The final is not taken

2) The student's standing in the course is passing.

3) I am notified by the student on or before the day of the final

that the final will not be taken.

4) The final is not taken because of a legitimate reason such as illness.
