General Chemistry, Sections 1 and 2
Syllabus for the fall 1999 semester
will be given the second hour of the class. In my experience the foremost problem in
the course is ability to handle comfortably arithmetic, algebra and word problems. Those
who have difficulties passing the background test are very likely to struggle for the rest
of the course, ostensibly failing chemistry but in reality falling behind because of not
understanding the tools of math and logic. My advice is to drop CHEM 210 right away (the
drop date is Friday of the first week of classes) and take mathematics instead. Taking
CHEM 110, in general, will not remedy this problem.
CHEMISTRY 210 Section 1 and 2 Fall 1999
08:00-08:50 M, W, F - Section 1
TENTATIVE LECTURE SCHEDULE
INSTRUCTOR: Dr. Petr Vanýsek; Office, Faraday West 418
OFFICE HOURS: 15:00-16:00 Monday, 15:00-16:00 Wednesday. Other times by appointment. I will help you with your problems but come to see me with questions and problems already at least partially prepared. Do not expect me to give you your own make-up class. Be prepared to share the office or the time with other students.
INSTRUCTOR RESPONSIBLE FOR THE LABORATORIES: Dr. D. Ballantine, Jr., Faraday West 424.
Recommended materials: A calculator with scientific notation, logarithms, goniometric and statistical functions (You probably have one already. Just check that you know how to use your own calculator. Each has its own idiosyncrasies that you have to master. Do not borrow somebody else's calculator immediately before a test unless you know how to operate it. Needless errors and lot of frustration is created if a calculator "deceives" you.).
Programmable calculators are acceptable during tests as long as they do not contain in any of their storage devices the course material subject to the testing. You cannot share a calculator during a test. Computers (laptops, notebooks, etc.) cannot be used during tests.
Have a calculator and a pad for calculations ready for each class period. The lecture will be always interspersed with your active participation.
For tests and quizzes it is assumed that everybody has a calculator, pencil No. 2 (for computer grading forms, if such are used), a pen (only answers written in permanent ink can be reconsidered if you suspect an error in grading of an essay question or expect reconsideration for partial credit), and substantial knowledge to answer correctly the questions.
Helpful for those insecure in mathematics are the following books: Miller, Lial, Schneider; Fundamentals of college algebra (MATH 110 book); Dorothy M. Goldish: Beginning mathematics for beginning chemistry, 4th Ed., Macmillan, New York, 1990.
SCHEDULE: Monday, Wednesday, Friday, - lecture, Recitations Monday or Wednesday, as shown:
Recitation schedule. All recitations held in Faraday 205
ATTENDANCE: Documented attendance is mandatory for the recitations. Each 3
documented absences will result in the loss of 50 points from the student's score. That
corresponds to lowering the class score by one letter grade! The instructor in charge will
keep attendance list. Late arrival or early departure is also an absence.
EXAMS AND GRADING:
Hour tests (3) 50% (300 points)
TOTAL (600 points)
There will be 4 quizzes, and some graded homework at the recitation session. The combined score from the recitation (maximum possible 100) will substitute for the hour test with the lowest score, if the recitation score is higher. A minimum grade of 60% in the laboratory is required to pass the course.
Finals: Section A (8 AM class) - Monday, 6 Dec. 1999 8:00-9:50
NOTE THAT TAKING THE FINAL TEST IS REQUIRED.
In general, cheating means presenting or using work which was not done entirely by you and, in the case of in-class examination, it includes also presenting or using your work that was written outside the classroom. You may not talk or pass notes to each other on any subject. Having other materials than those allowed for the work with you within reach during test or sharing calculators is cheating as well. Keep what you may need for the test within reach and keep what you should not have with you in your closed packs or better yet, do not bring it in. Remote communication devices should be turned off during lectures as a matter of courtesy to others. However, receiving or transmitting signals during tests is potential gateway for cheating. Anyone apprehended having such a device on this during a test will receive a zero on that test.
No smoking in the building, no food or drink in the class.
THERE WILL BE NO MAKE-UP TESTS
Note that the rule of replacing the worst test with the recitation score is your insurance against missing a test. There will be no make-up for a test for any reason. Do not inquire. If you have to miss a quiz for a substantial and veritable reason, ask the TA ahead of time about possible rescheduling. Those who take all the tests and quizzes are not curve busters for those who miss one. All are graded on their own merit. There is not a curve in the class.
Your class percentage will be calculated as the sum of all the points earned, divided by 6. The grades will be as follows:
A Outstanding competence 90% and more
