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.)

To determine what portion of the question you have correct, click on question score at the top of the assignment. Be sure to refresh question score after each submission. The volume of 4 g of gas at 200 K and 2 atmospheres is 2 liters. a. What is the volume of the gas if the temperature is increased to 400 K (n and P same as above)? 4 liters b. Complete the statement. If the temperature is increased, the volume of the gas will increase . c. Complete the statement. Temperature and volume are directly proportional. 2. 0.27/0.27 points | 1/5 submissions In the experiment shown here, 1.200 g of Cl 2 is present in the container. If the height of the column ( h ) is 446 mm , the temperature is 14 C , and the barometric pressure is 762 torr . Your answers should all contain three digits. There are 760 torr in an atmosphere. Use 0.0821 L*atm/K*mol as the ideal gas constant. The pressure of the gas in atmospheres is .416 atm. The number of moles of Cl 2 is .0169 mol....
