Unformatted text preview: Chemistry 310N Dr. Brent Iverson Final Exam May 14, 2010 NAME (Print): _____________________________ SIGNATURE: _____________________________ Please Note: This test may be a bit long, but there is a reason. I would like to give you a lot of little questions, so you can find ones you can answer and show me what you know, rather than just a few questions that may be testing the one thing you forgot. I recommend you look the exam over and answer the questions you are sure of first , then go back and try to figure out the rest. Also make sure to look at the point totals on the questions as a guide to help budget your time. Please print the first three letters of your last name in the three boxes You must have your answers written in PERMANENT ink if you want a regrade!!!! This means no test written in pencil or ERASABLE INK will be regraded. Please note: We routinely xerox a number of exams following initial grading to guard against receiving altered answers during the regrading process. FINALLY, DUE TO SOME UNFORTUNATE RECENT INCIDENCTS YOU ARE NOT ALLOWED TO INTERACT WITH YOUR CELL PHONE IN ANY WAY. IF YOU TOUCH YOUR CELL PHONE DURING THE EXAM YOU WILL GET A "0" NO MATTER WHAT YOU ARE DOING WITH THE PHONE. PUT IT AWAY AND LEAVE IT THERE!!! 20 19 18 17 16 15 14 13 12 (35) (25) (17) (22) (12) (17) (12) (16) (25) (16) (400) 11 Total T Score HW Total Grade (HW score + Exam Grade) % 10 (36) (15) 9 (30) 8 7 (14) 6 Page Points (17) 5 (14) (18) 4 (20) 3 2 (28) 1 (11) Honor Code The core values of the University of Texas at Austin are learning, discovery, freedom, leadership, individual opportunity, and responsibility.
