By completing this assignment, you can both practice for Exam 3 and use this assignment to replace a past or future assignment you may have scored low on. Remember that Exam 3 is on paper, and you'll only have 1 "submission". You'll be given this information on the Exam 3 cover sheet: PV = nRT R = 0.0821 L*atm/K*mol or 8.3145 J/K*mol 1 atm = 760 mm Hg = 760 torr K = C + 273.15 delta G = delta H - T * delta S A table of bond enthalpies. Chapter 9 Study Sheet A piece of advice: Students often get so concerned about mastering chapter 9, that they forget chapters 7 and 8 are also on the exam. Please don't miss easy questions from chapters 7 and 8, due to extreme concentration on chapter 9. Instructions The question submission scoring is as follows: Correct on first submission: full points Correct on second submission: full points Correct on third submission: full points Correct on fourth submission: 90% of points Correct on fifth submission: 80% of points Do NOT press 'submit all questions" when you are finished. This will do exactly as indicated, and submit all questions, reducing your score. The due date for this assignment is past. Your work can be viewed below, but no changes can be made. Extensions are no longer available for this assignment. (Automatic Extensions are only available within 2 days of the assignment due date.)
