Calculate the standard enthalpy change for the reaction between 25 mL of 0.1 M HCl and 25 mL of 0.1 M NaOH, assuming the reaction takes place in aqueous solution and is complete. The temperature of the solutions should be maintained at a constant 25°C during the reaction. (Assume the density of the solutions is 1 g/mL and the specific heat capacity of the solutions is 4.18 J/g°C).
