Calculate the enthalpy change when 50 mL of 2 M HCl solution reacts with excess NaOH according to the balanced chemical equation: HCl (aq) + NaOH (aq) → NaCl (aq) + H2O (l) Given that the specific heat capacity of the solution is 4.18 J/g°C, and the initial and final temperatures of the solution are 25°C and 35°C, respectively. Assume a density of 1 g/mL for the solution.
