The following information was obtained when carrying out an experiment to determine the Enthalpy of neutralization (ΔH) reaction between HCl and NaOH. 100 mL of 2.00 M HCl solution was added to 95.00 mL of 2.00 M solution of NaOH. The final temperature reached was 35.40 °C and the initial temperature at mixing was 22.15 °C. The density of the reaction mixture was 1.04 g/mL and the specific heat capacity was 3.89 J/g-°C. What is the enthalpy of neutralization reaction in kJ/mol?
