Zinc metal reacts with hydrochloric acid according to thefollowing balanced equation. Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g) When0.107 g of Zn(s) is combined with enough HCl to make 54.9 mL ofsolution in a coffee-cup calorimeter, all of the zinc reacts,raising the temperature of the solution from 22.0 ∘C to 24.0∘C.
Find ΔHrxn for this reaction as written. (Use 1.0 g/mL for thedensity of the solution and 4.18 J/g⋅∘C as the specific heatcapacity.)
