[1] In a coffee-cup calorimeter, 100.0 ml of 0.100 M Ba(NO3)2 and 100.0 ml of 0.100 M H2SO4 are mixed to yield the following reaction: $Ba^{2+}(aq) + SO_4^{2-}(aq) \rightarrow BaSO_4(s)$ The two solutions were initially at 23.50 °C, and the final temperature is 25.85 °C. Calculate the heat that accompanies this reaction in kJ/mol of BaSO4 formed. Assume that the combined solution has a mass of 200.0 g and has a specific heat capacity of 4.184 J/°C-g, and the heat capacity of the calorimeter is 35.2 J/°C. [2] Benzoic acid (C6H5COOH) has an energy of combustion of -3227 kJ/mol. When a sample of benzoic acid with mass 2.000 g is burned in a bomb calorimeter, the temperature increased by 1.978° C. Calculate the heat capacity of the calorimeter.
