Calculate the standard enthalpy change for the reaction in which 50.0 mL of 1.0 M HCl is mixed with 50.0 mL of 1.0 M NaOH in a constant pressure calorimeter using the following data: the temperature of the HCl and NaOH solutions are both initially 25.0 °C, and the temperature of the mixture increases to 32.0 °C. The specific heat of the solution is 4.18 J/(g·°C) and the density of the solution is 1.00 g/mL. The reaction is: HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)
