CH1100 General Chemistry Exam #2 March 23, 2005 There is one and only one best answer for each question, and there is no penalty for guessing. Only non-programmable calculators are allowed. Read all answers. If two or more answers are approximately correct, choose the best or most complete answer given. Be sure to transfer accurately the answers to your computer-graded answer sheet. Do not make any extra marks on your answer sheet. The computer will pick up any extra marks (numbers circled or checked) and count them as a double answer and the answer will be graded as incorrect. When you are told to begin, check to see that your exam has 9 pages and 31 questions . Print your name clearly on Side 1. ¼ Do not use Side 2. » Write your Student ID & fill in the slots. Use a #2 pencil! Be sure to make DARK marks!
