Answer:

D) hydrochloric acid.

Explanation:

  • The balanced equation for the mentioned reaction is:

<em>Zn(s) + 2HCl(aq) → ZnCl₂(aq) + H₂(g),</em>

<em></em>

It is clear that 1.0 moles of Zn react with 2.0 moles of HCl to produce 1.0 moles of ZnCl₂ and 1.0 mole of H₂.

  • From stichiometry; Zn reacts with HCl with (1: 2) molar ratio.

<em>∴ 2.0 mol of Zn (the remaining 2.0 mol is in excess) react completely with 4.0 mol of HCl with (1: 2) molar ratio.</em>

<em />

So,

the limiting reactant is HCl and the excess reactant is Zn.

<em>Thus, the right choice is: D) hydrochloric acid.</em>
