In a coffee-cup calorimeter, 100.0 mL of 1.0 M NaOH and 100.0 mL of 1.0 M HCl are mixed. Both solutions were originally at 24.6ºC. After the reaction, the final temperature is 31.3ºC. Assuming that all the solutions have a density of 1.0 g/cm3 and a specific heat capacity of 4.18 J/ºC.g, calculate the enthalpy change for the neutralization of HCl by NaOH. Assume that no heat is lost to the surroundings or to the calorimeter.
