When 0.107 g of Zn(s) combines with 56.4 mL of HCl(ag) in a coffee cup calorimeter, all of the zinc reacts, which increases the
temperature of the HCl solution from 23.2 °C to 24.8 °C:
Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)
Calculate the enthalpy change of the reaction Arxn in J/mol. (Assume the volume of the solution doesn't change, density of the
solution is 1.00 g/mL and the specific heat capacity of solution is 4.184 J/gºC.)
