Question

1. Zn(s) + HCl(aq) -> ZnCl₂(aq) + H₂(g)

Answer 1

Answer:

Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g) ... balanced molecular equation

Zn(s) + 2H+(aq) + 2Cl-(aq) ==> Zn2+(aq) + 2Cl-(aq) + H2(g) ... balanced ionic equation

Zn(s) + 2H+(aq) ==> Zn2+(aq) + H2(g) ... BALANCED NET IONIC EQUATION

Explanation:

In the given equation - Zn(s) + 2Hcl(aq)-----> Zncl2(aq) + H2(g), Zinc (Zn) is a reductant metal that displaces hydrogen (H2) from aqueous solution of Hydrochloric acid (HCl).
