Question

what information is conveyed by the following equation Zn(s) + 2Hcl(aq)-----> zncl2(aq)+h2(g).

Answer 1

Answer:

Given chemical equation is a 'single displacement reaction', in which a non-metal is displaced by a metal.

Here, non-metal is hydrogen which is evolved as gas. It is displaced by the metal zinc.

Explanation:

Generally, a single displacement reaction follows the below pattern:

A + BC ----> B + AC

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).

Answer 2

Explanation:

Answer: Here, non-metal is hydrogen which is evolved as gas. It is displaced by the metal zinc. 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).
