.When solutions of an acid and a base are mixed, heat is released. Using a coffee-cup calorimeter, 100.0 mL of 0.100 mol/L HCI are mixed with 100.0 mL 0.100 mol/L NAOH solution. The initial temperature of the solutions were 22.6 °C, and the temperature after mixing was 32.4 °C. Calculate the molar enthalpy of neutralization for the reaction: HCI (aq) + NaOH (aq) → NaCI (aq) + H,0 (1)
