17 marksPage 8ProblemMixing 100 g hydrochloric acid with 100 g aqueous sodium hydroxide results in the reaction shown. The temperature of both solutions before mixing was 23.79°C.
The temperature of the solution after mixing was 31.56°C. Calculate the heat of reaction.

HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O
