Zinc metal (Zn) will react with aqueous hydrochloric acid (HCI aq) to produce aqueous zinc chloride (ZnCl2 aq) and hydrogen gas (H2). Which of the following isthe complete, balanced equation for this reaction?1. 2 HCI (aq) + 2 Zn (s) > 2 H2 (g) + ZnCl2 (aq)2. HCI (aq) + Zn (s) > H2 (g) + ZnCl2 (ag)3. 2 HCI (aq) + Zn (s) › 2 H2 (g) + ZnCl2 (ag)4. 2 HCI (aq) + Zn (s) › H2 (g) + 2 ZnCl2 (ag)5. 2 HCI (aq) + Zn (s) › H2 (g) + ZnCl2 (ad)

Answer:

[tex]5[/tex]

Explanation:

Here, we want to get the equation of the reaction between Hydrochloric acid and Zinc metal

Zinc metal displaces the hydrogen from hydrochloric acid to form zinc chloride

We have the equation of reaction as:

[tex]2HCl_{(aq)}\text{ + Zn}_{(s)}\text{ }\rightarrow\text{ ZnCl}_{2(aq)}\text{ + H}_{2(g)}[/tex]
