8. When 23.6g of calcium chloride, CaCl2, was dissolved in water in a constant-pressure calorimeter, the temperature rose from 25. 2° to 38.9°C. If the heat capacity of the solution and calorimeter is 1258J/C, what is the enthalpy change when 1.20 mol of calcium chloride dissolves in water? The solution process is 2+ CaCl2(s) + → Ca (aq) + 2cī
