Calculate the standard enthalpy change for the reaction of 25.0 mL of 0.100 M HCl with 25.0 mL of 0.100 M NaOH at 25°C, given that the specific heat capacity of the solution is 4.18 J/g°C and the density of the solution is 1.00 g/mL. The balanced chemical equation for the reaction is:HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l) Assume the heat of the reaction is absorbed by the solution and the reaction has reached equilibrium.
