Final answer:

No additional zinc will be produced in the displacement reaction between zinc and hydrochloric acid, as the reaction forms zinc chloride and hydrogen gas, not more zinc metal. Consequently, the correct answer is 0.0 grams of zinc will be produced.

Step-by-step explanation:

The question is about a displacement reaction where zinc metal reacts with hydrochloric acid (HCl). The balanced chemical equation for this reaction is:

Zn(s) + 2HCl(aq) → ZnCl₂ (aq) + H₂(g)

In this reaction, zinc displaces the hydrogen in hydrochloric acid, forming zinc chloride and hydrogen gas. Since the zinc is being used up to produce zinc chloride, the amount of zinc will not increase. Therefore, no additional zinc will be produced beyond what was initially used. The correct answer to the question of how much zinc will be produced is:

a) 0.0 grams

The question describes a chemical reaction where the reactants are zinc and hydrochloric acid to produce zinc chloride and hydrogen gas. The reaction is not creating additional zinc, so the amount of zinc remains the same as what was initially added to the reaction.
