A dilute solution of hydrochloric acid with a mass of 605.91 g and containing 0.34080 mol of HCl was exactly neutralized in a calorimeter by the sodium hydroxide in 610.68 g of a comparably dilute solution. The temperature increased from 16.109 to 20.554 °C. The specific heat of the HCl solution was 4.031 J·g-1·°C-1; that of the NaOH solution was 4.046 J·g-1·°C-1. The heat capacity of the calorimeter was 77.99 J·°C-1.

a) find the balanced equation for the reaction, include states. 

Use the data above to calculate the heat evolved. What is the heat of neutralization per mole of HCl? Assume that the original solutions made independent contributions to the total heat capacity of the system following their mixing.

b) ΔH = _____ kj/mol
