Part A Zinc metal reacts with hydrochloric acid according to the following balanced equation. Zn(s) + 2HC1(aq)→ZnCl2 (aq) + H2 (9) Find A, H for this reaction as written. (Use 1.0 g mL-1 for the density of the solution and 4.184 J g¬1 °C-1 as the specific heat capacity.) Express your answer in kilojoules per mole to two significant figures. When 0.124 g of Zn(s) is combined with enough HCl to make 52.7 mL of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 22.4 °C to 24.4 °C. A,H = kJ mol-1
