Zinc reacts with hydrochloric acid according to the following balanced chemical equation:

Zn (s) + 2 HCl(aq) → ZnCl2(aq) + H2(g)

A student needs to react 0. 265 mol Zn with hydrochloric acid. Calculate the minimum number of moles of HCl required,

assuming all the zinc reacts?

Enter your answer to three significant figures. Do not include units.

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.
