Unformatted text preview: 1 Chemistry 301 Name _________________________ First Hour Exam October 10, 2002 This is a closed-book, closed-note exam. You may use a basic calculator (no memories or alphanumerics), the equation sheet and periodic table on the back of this exam, but no other materials other than your writing instrument. Use of other materials or looking on another's paper will result in your failing this course. Show all of your work. If you have a question, raise your hand and the instructor will come to your seat. Do not come to the front of the room. Keep your eyes on your own paper and keep your exam covered with your periodic table.
