A student mixes 50.0 mL of 1.00 M HCl with 50.0 mL of 1.00 M NaOH in a coffee-cup calorimeter. The temperature increases from 22.0°C to 28.8°C. Assume the solution density is 1.00 g/mL and its specific heat capacity is 4.18 J/g·°C. (Ignore the heat absorbed by the calorimeter)What is the approximate enthalpy change, ΔH, for the neutralization reaction?A. −28.4 kJ/molB. −56.8 kJ/molC. +28.4 kJ/molD. +56.8 kJ/molE. −2.84 kJ/mol
