General Chemistry, Sections 1 and 2 Syllabus for the fall 1999 semester
Background exam
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. Sample of an old background test.
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;
Recitation schedule. All recitations held in Faraday 205
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.
CHEATING:
No smoking in the building, no food or drink in the class.
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 (revised text 24 August 1999) A sample of an old background test: The original text has been written using T Mathematical skills 1. Which of the following gives the answer x = 3? a) 2x - 7 = x + 6 b) 2.5 x + 3 = 15 - 1.5x c) 4x + 0.2 = 6.6 d) 5x + 9 = 2x + 30 e) 2.1x +1.3 = 5x - 3 2. Which of the following gives the answer x = 2 - 2y? a) 3x + y = 27 b) 5x - 2y = 15 c) x + yz = 0.5 d) ax - y = bz e) 3x + 6y + 4 = 10 3. Which of the following gives the answer y = 1 - 0.5x? a) 3x + y = 27 b) 5x - 2y = 15 c) x + yz = 0.5 d) 3x + 6y + 4 = 10 e) ax - y = bz 4. Which of the following gives the answer z = !!!!-!? a) 3x + y - z = 27 b) 5x - 2y = 15 + z c) 3x + 6y + 4 = 10z d) x + yz = 0.5 e) ax - y = bz 5. [H a) 10 b) 10 c) 10 d) 10 e) 10 6. Which of the following yields the answer x = - y ? a) ! + ! = 15 b) ! + ! = 0 c) ! + 3 = y d) ! + ! = 1 e) ! + ! 7.

Substitute the values given into the equation and solve for the remaining unknown: !!! = 2.0; a a) 72 b) 24 c) 18 d) 1 e) 9 9. Write an equation to express the following: In 7 years, Tom will be 1.5 times as old as Ann. T stands for Tom's present age, A for Ann's present age. a) A + 7 = 1.5(T + 7) b) A + 7 = 1.5T c) T + 7 = 1.5(A + 7) d) A + T = 1.5x7 e) 7 + T = 1.5A 10. A bit of multiple choice logic.
