Prelab 1. Zinc metal reacts with hydrochloric acid according to the balanced equation: Zn (s) + 2 HCI (aq) ZnCl2 (ag) + H2 (g) When 0.103 g of Zn (s) is combined with enough HCl to make 50.0 mL of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 22.5°C to 23.7°C. Find AH for this reaction as written. Use 1.0 g/mL for the density of the solution and 4.18 J/(g-°C) as the specific heat capacity. Ignore the heat absorbed by the calorimeter.
