5. When 1.00L of a 1.00 M Ba(NO3)2 solution at 25.0oC is mixed with 1.00 L of a 1.00 M Na2SO4 solution at 25.0oC in a calorimeter, the white solid, BaSO4 forms and the temperature of the mixture increases to 28.1oC. Assuming that the calorimeter absorbs only a negligible quantity of heat, that the specific heat capacity of the solution is 4.18 J/oC g and that the density of the final solution is 1.0 g/mL, calculate the enthalpy change per mole of BaSO4 formed.

In a constant-pressure calorimeter of negligible heat capacity, 25 mL of 1.00 M CaCl2 is mixed with 25 mL of 2.00 M KF, resulting in solid CaF2 precipitating out of the solution. During this process, the temperature of the water rises from 25.0°C to 26.7°C. Assume the specific heat capacity of the solution is 4.184 J/°C•g and the density of the solution is 1.00 g/mL. Calculate the enthalpy of precipitation in kJ per mole of CaF2 precipitated.
