Zinc metal reacts with hydrochloric acid according to the following balanced equation: Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g)Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g) When 0.122 gg of Zn(s)Zn(s) is combined with enough HClHCl to make 51.8 mLmL of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 22.1 ∘C∘C to 24.4 ∘C Find ΔHrxnΔHrxn for this reaction as written. (Use 1.00 g/mLg/mL for the density of the solution and 4.18 J/(g⋅∘C)J/(g⋅∘C) as the specific heat capacity.)

Question
Zinc metal reacts with hydrochloric acid according to the following balanced equation:
Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g)Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g)
When 0.122 gg of Zn(s)Zn(s) is combined with enough HClHCl to make 51.8 mLmL of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 22.1 ∘C∘C to 24.4 ∘C
Find ΔHrxnΔHrxn for this reaction as written. (Use 1.00 g/mLg/mL for the density of the solution and 4.18 J/(g⋅∘C)J/(g⋅∘C) as the specific heat capacity.)
