Unformatted text preview: Chem 125 Dr. Retsek Spring 2008 Study Guide for Exam Three For Exam three, you will need a non-programmable, non-graphing scientific calculator (You will NOT be allowed to share or borrow a calculator or use a cell phone for a calculator during the exam. Anyone who does will get a zero on the exam.) a #2 pencil Exam 3 Protocol: (same as Exam 1 and 2) At your desk, only have your pencil, eraser, and calculator. Remove the calculator from any covers or cases and leave those in your backpack as well. You will be given a scantron, periodic table, and the equation sheet posted on the webpage. All needed K a and K b values will be on the equation sheet NOT in the problems. Read each question and the directions carefully. The directions may change from problem to problem. If you dont know how to do a problem, skip it and move on. Careful of the time. Some of the multiple choice questions will be worth only a few points but could take a while. Try to do the big point problems that you know how to do first. Be sure any work you do is clear and easy to follow. I am not a mind reader. Follow all of the rules of significant figures and label all answers with the appropriate units. Exam 3 will cover chapters 17 (sections 4-6), 20 (section 4 although you need to understand the previous three sections) 18, 19 (section 2 on titrations), 4 (section 4.5), and 21 (sections 1 and 2), any problems assigned from those chapters, worksheets, and anything covered in lecture. The exam will consist of multiple choice questions, some true-false questions, some short answer questions, and some problems. etc. Dont ask me too many specific questions because I havent written the exam yet!...
