Zinc dissolves in the acid according to the balanced reaction:
Zn(s) + 2H^+(aq) -> Zn^2+(aq) + H2(g)
Describe what enthalpy change, per mole of zinc, for the above reaction per mole of zinc. A sample of zinc is placed in the ice calorimeter if 0.0657g of zinc causes a decrease of 0.109 ml in the ice/water volume of the calorimeter.
