Text:   Kotz, J.C.; Treichel, P.M.; Weaver, G.; Chemistry and Chemical Reactivity, 6 ^th ed., Thomson Learning: U.S.A., 2006.

Outcomes:

This course will introduce the student to the laws, theories, and principles of general chemistry.  Problem solving is strongly emphasized.  Upon successful completion of this course, a student should be able to:

1.       Use the Kinetic Molecular Theory to explain the behavior of gases.

2.       Explain the behavior of matter using the concept of intermolecular forces.

3.       Understand the formation and behavior of solutions.

4.       Understand the kinetics of a reaction and be able to distinguish between the reaction orders.

5.       Understand equilibrium and use it to calculate solution concentrations under a variety of conditions.

6.       Understand acids and bases and their behavior in solutions.

7.       Understand buffers and their importance in living systems. 

8.       Apply equilibrium concepts to calculate concentrations and pHs of buffer systems and acid/base solutions.

9.       Understand thermodynamic concepts and be able to use them to make predictions about reactions.

10.   Understand basic electrochemical concepts.

11.   Understand the radioactive nature of atomic nuclei

12.   Communicate experimental findings verbally and in writing

13.   Work as a collaborative member of a group

Assignments:

The student should read the relevant chapters of the text as given in the course outline.  Each chapter in the text has examples of the types of problems encountered, followed by “Exercise” problems for the student to solve.  These are a great opportunity to try out problems:  the answers are given in Appendix N.

The Study Questions at the end of each chapter should be worked out.  Answers to the blue-numbered Study Questions are given in Appendix O at the back of the text. A list of suggested homework problems is available. I will not collect this homework but you must be able to do these problems to pass the tests.   Tests and quizzes will depend heavily on these types of questions.  I have included a list of recommended homework problems.

The CD-ROM included with the textbook contains interactive tutorials to help you understand fundamental concepts and help you problem-solve your way to understanding.  The CD-ROM is an excellent resource – use it.

You are responsible for reading ahead in the textbook before we cover the material in class.  I will call on students to answer questions.  Be PREPARED.

Service:

Five percent of your grade this semester will be based on your participation in community service projects. The full five percent will be given for three (3) hours of this type of community service.  This is not extra credit, but is a requirement of the course. There will be a variety of opportunities for service including: 

·         judging science fairs

·         assisting classroom teachers with in-class projects

·         performing experiments or demonstrations in elementary classrooms

·         assisting community service organizations doing scientific testing, experimental design, etc.

 I will help you find suitable opportunities for service and will help you to document this service so that you are given the proper credit. You are not limited to the service opportunities that I make available, but may participate in local school or community activities by sharing your scientific knowledge.  Please clear such activities with me in advance so that I can be sure that your activities qualify for credit.  Activities that are not of a scientific nature or requiring a scientific background will not be given credit.  In addition to documenting your service, you must also write a one-page reflection (typed, single spaced) on your community service experience and how your science background helped you complete your service.  Your community service must be documented, approved by me, and completed by April 27, 2006.

Attendance:

Attendance is mandatory.  Excessive absence can be cause for loss of a grade or failure.  Please contact me if you will be (or have been) absent.  Absence from a test is excusable only through a certified excuse and the test must be made up. You must notify me of your reason for missing a test BEFORE the exam is  given (or as soon as possible thereafter, if a medical emergency).  Tests not made up will result in failure of the course.

HELP!

My office hours are listed at the top of this page.  If these are inconvenient for you, please make an appointment with me for another time.  You can come with specific questions or just to go over problems.  Don't let yourself fall behind before you seek help!!  You can also leave me questions at the e-mail address given at the top of the page.  I check my mail every day so I will be sure to get your message and reply as soon as possible.  You can also use my e-mail to set up times to meet, etc.  Other avenues: speak with your advisor about tutorial help or you can get help at the college skills center at 569-3177.

Grading:

There will be 3 hourly exams and daily quizzes.  The average of the quizzes will count as one exam.  The lowest exam grade (hourly or quiz average) will be dropped.  Exams and quizzes count for 50% of your final grade.  A comprehensive final will count for 20%, a community service project is worth 5%, and the laboratory grade makes up the other 25% of your total grade.

     tests/quizzes        50%

LABORATORY

Laboratory Manual: Cooper, M.M. Cooperative Chemistry Laboratory Manual , 2 nd ed., McGraw-Hill: New York , 2002.

Attendance in lab is MANDATORY . The lab makes up 25% of your total grade for chemistry 152. You must see me about any EMERGENCIES that arise requiring you to miss a lab. Missed labs may be made up at the discretion of the instructor. Missed labs may be sufficient cause for failure of the course. Arrangements for missed labs are the responsibility of the student and must be made with the instructor as soon as possible, preferably before the lab takes place. Missed labs will negatively affect the laboratory grade.

Safety glasses must be worn at all times in the laboratory. Contact lenses should not be worn in the lab. Please advise me if this is a problem.
