Calculate the standard enthalpy change for the neutralization of HCl with NaOH, given that the heat of formation of water is -285.8 kJ/mol, the heat of formation of NaCl is -411.1 kJ/mol, and the initial concentrations of HCl and NaOH are 1.0 M.

Calculate the standard enthalpy change (ΔH°) for the reaction where 1 mol of solid sodium hydroxide (NaOH) dissolves in excess water to produce 1 mol of aqueous solution and releases heat. Given that the standard enthalpy of formation (ΔH°f) for NaOH(s) is -425.6 kJ/mol, the heat capacity of the aqueous solution is 4.18 J/gK, and the change in temperature (ΔT) is observed to be 8.0°C for 250 g of the solution.
