When 0.113 g of Zn(s) is combined with enough HCl to make 52.3 mL of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 21.8 oC to 24.5oC.
Find ΔH for this reaction as written, i. e., DH for 1 mol Zn. (density of soln = 1.00 g/mL and specific heat = 4.18 J/(goC))
ADDITIONAL INFO:
Zinc metal reacts with hydrochloric acid: Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g)
