General Chemistry, Sections 1 and 2 (A syllabus from Spring 1998 that is being reworked into the 1999 version)
Background exam is given the second hour of the class. In my experience the foremost problem in the course is ability to handle comfortably arithmetics, algebra and word problems. Those who have difficulties passing the background test are very likely to struggle during the course. My advice is to drop CHEM 210 right away and take mathematics instead. CHEM 110, in general, will not remedy this problem. 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; b=3.0, c=15 a) 10/3 b) 3.0 c) 3/10 d) 2.24 e) 25 8. 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. Only one answer is correct. Which one is it? a) e) is correct b) this one is correct c) b) is correct d) c) is not correct e) None of the above

A full container holds 5/8 gallon of liquid. If the container is 4/5 full and then 25% of the liquid is lost due to evaporation, how much liquid is left in the container? a) 1/4 gallon b) 3/8 gallon c) 1/2 gallon d) 5/8 gallon e) 3/4 gallon 13. In six years, Tony will be twice as old as he was 4 years ago. How old will tony be in 4 years? a) 12 years b) 14 years c) 16 years d) 18 years
14. Julie's collection of 50 coins consists of dimes and quarters totaling $ 7.10. How many more dimes than quarters does Julie have? a) 14 b) 20 c) 22 d) 26 e) 36 15. I have enough money to buy 45 bricks. If the bricks each cost 10 cents less, I could buy 5 more bricks. How much money do I have to spend on bricks? a) $ 100 b) $ 50 c) $ 45 d) $ 40 e) $ 35
16. If i = -1 , simplify !-!-! : a) !-!!! b) !-!!! c) !-!-! d) !-!-! e) --!!- 17. It costs $ 100 to produce certain amount of fruit. For how much must the fruit be sold, to realize a 20 % profit of the selling price? a) $ 80 b) $ 120 c) $ 125 d) $ 135 e) $ 180 18. Five oranges cost three dollars. What is the price of seven oranges? a) $ 2.17 b) $ 7.00 c) $ 4.20 d) $ 5.30 e) $ 1.05 19. How many three-cent stamps are in a dozen? a) 4 b) 3 c) 12 d) 36 e) 60 20. Simplify 81 a) 60.75 b) 108 c) 27 d) 350.5 e) 132860

__________
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;
Hour tests (3) 50% (300 points) Comprehensive final test 33% (200 points) Laboratory 17% (100 points) TOTAL (600 points) There will be 11 quizzes, each worth 10 points. The sum of the quiz grades (up to 110 points) will substitute for the hour test with the lowest score, if the quiz sum is higher. A minimum grade of 60% in the laboratory is required to pass the course. Bonus credit may be available through taking computer aided practice. Watch for a specific announcement in the class. NOTE THAT TAKING THE FINAL TEST IS REQUIRED.
CHEATING:
Note that the rule of replacing the worst test with the quiz score is your insurance against missing a test. Similarly, since even with one missed quiz the total may add up to a happy 100 points, there is a built-in provision for missing a written work. Hence, there will be no-makeups for any reason. Do not inquire. 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 B Above satisfactory competence 80% to 89.99% C Satisfactory level of competence 70% to 79.99% D Marginally satisfactory competence 60% to 69.99% F Unsatisfactory level of competence < 60% (or <60% in lab.)
