8. (12 pts) A 0.05-mol sample of solid benzoic acid (C6H5COOH)

8. (12 pts) A 0.05-mol sample of solid benzoic acid (C6H5COOH) is burned in an excess of oxygen gas to yield carbon dioxide (gas) and water (liquid) in a constant-volume calorimeter at room temperature (25C). The amount of heat released is observed to be 255kJ. Assume all gases behave ideally, and assume that the volume of any liquids or solids is negligible compared to the volume of the gases. a) Write and balance the equation for this combustion. b) Calculate the change in internal energy for the combustion of 1.0mol of benzoic acid at this temperature. c) Using your answer from part b, calculate the enthalpy change for the combustion of 1.0mol of benzoic acid at this temperature. Hint: given the assumption stated above, focus on the gases here as you solve the
