Answer:

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 50.9 mLmL of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 21.5 ∘C∘C to 24.2 ∘C∘C.
