Question

5.
Based on the equation below, which of the following statements best describes what should be observed as the reaction takes place?
Zn(s) + 2HCl(aq) ZnCl2(aq) + H2(g)

A)Bubbles forming from chlorine gas production
B)Chlorine forming a solid precipitate
C)Solid zinc dissolving
D)Bubbles forming from hydrogen gas production

Answer 1

Answer :

(D). Bubbles forming from hydrogen gas production.

Explanation :

When zinc reacts with hydrochloric acid to produce zinc chloride and release a large amount of bubbles forming in the production of hydrogen gas.

We know that when metal reacts with any acids to form salt and hydrogen gas. If metal reacts with strong acid, it produces a large amount of bubbles forming in the production of hydrogen gas. If metal reacts with weak acid, it produces a small amount of bubbles forming in the production of hydrogen gas. It depends on acids if it is strong, it produces a large amount of hydrogen bubbles and if it is weak, it produces a small amount of hydrogen bubbles.
