Calculate the standard enthalpy change for the reaction in which 50.0 mL 0.20 M HCl(aq) is mixed with 50.0 mL 0.10 M NaOH(aq) in a constant pressure calorimeter. Given that the density of both the solutions is 1.00 g/mL and the specific heat capacity of the mixture is 4.18 J/g°C. Assume the temperature change to be negligible.
