Zinc metal reacts with hydrochloric acid according to the following reaction: % Zn (s) + HCI (aq) → ZnCl2 (aq) + Hz (g) If 0.9807 g of zinc is combined with 120. mL of 0.250 M HCI in an insulated calorimeter, the temperature rises from 24.9 °C to 36.3 °C. Assume the density of the solution formed is 1.00 g/mL. a. Calculate the total heat released (g) in this reaction, in Joules. b. Calculate the enthalpy of the reaction, AHran, in kJ/mol HCI.

Zinc metal reacts with hydrochloric acid according to the following reaction:
% Zn (s) + HCI (aq) →
% ZnCl2 (aq) + % H2 (g)
If 0.9807 g of zinc is combined with 120. mL of 0.250 M HCl in an insulated calorimeter, the temperature
rises from 24.9 °C to 36.3 °C. Assume the density of the solution formed is 1.00 g/mL.
a. Calculate the total heat released (g) in this reaction, in Joules.
b. Calculate the enthalpy of the reaction, AHpan, in kJ/mol HCI.
