Exam 2 Review 1. Fill in all blank boxes in the following table. You may use appropriate short-hand notation for the electronic configurations. Element Atomic Ground # Of core Z effective # Unpaired Number Electronic electrons Electrons Configuration Si Cl Ca 2) The pressure in a natural gas tank is maintained at 2.20 atm. On a day when the temperature is 15°c, the volume of the gas in the tank is 3.25cm3. What is the volume of the same quantity of gas on a day when the temperature is 31°c? 3) A 0.5 mol sample of oxygen is confined at 0°c and 1 atm in a cylinder with a movable piston. The piston compresses the gas so that the final volume is half the initial volume is half the initial volume and the final pressure is 2.2 atm. What is the final temperature of the gas in degree Celsius? 4) The pressure on the surface of Titan is 1220 torr. The atmosphere consists of 82 mol percent N2, 12 mol percent Ar and 6.0 mol percent CH4. Calculate partial pressure of each gas. 5) Which of the following conditions might we except a gas to not behave like an ideal gas? a. High temperature b. Low temperature c. High pressure d. Both (b) and (c) e. All of them
