Calculate the standard enthalpy change for the reaction between 50.0 mL of 0.200 M HCl(aq) and 50.0 mL of 0.300 M NaOH(aq) at 25°C. The heat capacity of the calorimeter is 9.60 J/°C and the temperature change observed is 4.00°C. Also, assume that the density of both solutions is 1.00 g/mL and that the heat capacity and density of the final solution are the same as that of water.
