Name MIDTERM 1 (Page 2 of 10) Part I: Multiple Choice, Concepts (5 points each) Select the best answer and enter your choice on the cover sheet – No partial credit 1. The units of heat capacity are a. K/J or o C/J. b. J/K or J/ o C. c. J/g·K or J/g· o C. d. J/mol. e. g·K/J or g· o C/J. 2. Of the following, which one is a state function? a. H b. q c. w d. heat e. none of the above 3. Consider ethane, C 2 H 6 (g), which has a standard enthalpy of formation -84.68 kJ/mole and ethanol, C 2 H 6 O(l) with standard enthalpy of formation -277.7 kJ/mole. Without performing a calculation we can conclude that the complete combustion of one mole of ethane should yield: a. less quantity of heat than the complete combustion of one mole of ethanol. b. more quantity of heat than the complete combustion of one mole of ethanol. c. same quantity of heat as the complete combustion of one mole of ethanol. d. not enough information to make a conclusion. e. 2 mol CO and 3 mol H 2 O. 4. Which one of the following derivatives of ethane has the highest boiling point? a. C 2 Br 6 b. C 2 F 6 c. C 2 I 6 d. C 2 Cl 6 e. C 2 H 6 5. Cesium chloride crystallizes in a body-centered cubic unit cell with a Cs + ion at the center of the unit cell and Cl - ions at the corners. What is the coordination number of Cs + in this structure?
