Determining the Theoretical Heat of Neutralization Using Hess' Law AH® for HCl(aq), NaOH(aq), H2O(l), and NaCl(aq) are -167.16, -470.11, -285.83, and -407.27 kJ/mol, respectively. Use Hess' law to calculate the heat of neutralization in kJ/mol. AHRx = H; (products) - H; (reactants) NaOH(aq) + HCl(aq) → HOH(1) + NaCl(aq) Heat of Formation -470.11 - 167.16 -407.27 kJ/mole Show all your calculations below. Your result will be considered as the "literature" value.

Additional Problem 6.098 Your answer is partially correct. Try again. A dilute solution of hydrochloric acid with a mass of 614.08 g and containing 0.30664 mol of HCl was exactly neutralized in a calorimeter by the sodium hydroxide in 618.91 g of a comparably dilute solution. The temperature increased from 16.663 to 19.946 °C. The specific heat of the HCl solution was 4.031 Jug-1.°C-1; that of the NaOH solution was 4.046 Jug-1.00-1. The heat capacity of the calorimeter was 77.99...
