Course Description

Chemistry 142 is the second semester of a yearlong course in General Chemistry. The first semester is Chemistry 141. If your major is a physical science, a life science, engineering, premedical, predental, or preveterinary, you are probably required to take both semesters.

In General Chemistry basic principles of chemistry are stressed. In Chemistry 142 the main theme is energy. Recall that in Chemistry 141 the main theme was the structure and composition of matter. Energy is a part of all chemical processes. Energy is often the critical ingredient in making a process take place or is the "product" of interest.

We will discuss the following topics:

    1. Gases
    2. Thermochemistry
    3. Kinetics
    4. Gas Phase Equilibrium
    5. Electrochemistry
    6. Nuclear Chemistry

A qualitative (nonmathematical) understanding of the basic concepts will be stressed for all topics. In addition all topics will involve mathematical problem solving.

Course Objectives

Theories of science are formulated from experimental observations. Lectures and labs are designed with this in mind. In lectures, relevant demonstrations of chemical phenomena are conducted BEFORE current theories are invoked to explain the observations. In laboratories you have the opportunity to make your own observations and then interpret these observations in subsequent laboratory reports using theories presented in lectures.

To learn and be successful in this class, you should do the assigned reading, in chapter exercises, lecture practice exercises, homework, quiz problems, sample exams, lab experiments and lab reports.

There are 15 LAB EXPERIMENTS. You are expected to do all the laboratories. A lab report is required for each experiment.

Methods of Evaluation

Your grade is based on written exams (80%), lab reports (about 13%) and quizzes (about 7%).

A total of six exams, one per topic listed above, will be given. The exams will be worth 200 points each for a total of 1200 points.

The total points of all 15 labs will be 200 points, the equivalent of one exam.

The point value of the quizzes is 100.

Grading Policy

Total points for the class is 1500.

You may take one make-up exam to replace your worst exam, whether it is a poor exam or a missed exam. Make-up exam scores will replace original exam scores. The make-up exam will be over the same topic in which you are trying to raise your score. Make-up exams will be given during the 11th and 17th weeks. If one of your first 3 exams is very low, it makes sense to make up your low exam during the 11th week. Otherwise, it is probably better to wait until the 17th week.

Grades will be based on the following scale:

A 1500 1320 100% - 80%
B 1319 – 1140 88% – 76%
C 1139 – 960  76% – 64%
D 959 – 780   64% – 52%
F 779 – 0      52% – 0%




Attendance will be taken at the beginning of class. Late arrival at class will be noted as an absence.

If a student misses more than six hours of class, he/she will be dropped for excessive absence or will lose one grade level for each missed hour beyond six.
