A common laboratory reaction is the neutralization of an acid with a base. When 49.6 mL of 0.500 M HCl at 25.0°C is added to 52.0 mL of 0.500 M NaOH at 25.0°C in a coffee cup calorimeter (with a negligible heat capacity), the temperature of the mixture rises to 28.2°C. What is the heat of reaction per mole of NaCl (in kJ/mol)? Assume the mixture has a specific heat capacity of 4.18 J/(g·K) and that the densities of the...
