If 33mL of 1.20M HCL is added to 42mL of a solution containing excess sodium hydroxide in a coffee cup calorimeter. The solution temperature, initially at 25.0C, rises to 31.8C. Give a thermochemical equation, including? H as well as then give the Enthalpy change H, evolved per mole HCL.

For simplicity, Presume the heat capacity as well as density of final solution are those of water. Also presume that the total volume of the solution equals the sum of the volumes of HCL (aq) and NaOH (aq).)
