If a reaction occurs, what will be the products of the unbalanced reaction below?Zn(s) + HCl(aq) -->
irakobra [83]

The products will be ZnCl_2(s) + H_2(g)

<h3>Chemical reactions</h3>

Zn is higher than hydrogen in the reactivity series. Thus, it will be able to displace hydrogen from the acid.

The equation of the reaction becomes: Zn(s) + HCl(aq) -- > ZnCl_2 (s) + H_2 (g)

Hydrogen gas is released as a result. In fact, it is one of the ways of preparing hydrogen gas in the laboratory.
