Unformatted text preview: EXAM 1 Dr. Krueger (CHEM 121) Remove me 10 February 2006 (100 pts) put name on the new first page Instructions: Do not open the main portion of the test until you are told to do so. The first three pages consist of equations and tables for your use. You may carefully remove them now. Finally, write your name on what is now the front cover of this test and wait until you are told to open the exam. When you are told to proceed, first scan over all the questions and make sure that you have 16 questions written on the 7 pages following the page you wrote your name on. Please make sure there are no books, notes or bags around you. Place all items, except for your calculator and writing implements off to the side of the room. If you have a programmable calculator, please delete all programs in memory now. Hint: Do the problems you feel most comfortable with first. Show all calculations clearly, and write down units everywhere to receive full credit. Partial credit will be given if you set the problems up correctly.
