Question

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) to ZnCl2 (aq)+ H2(g)Solid zinc dissolvingBubbles forming from chlorine gas productionBubbles forming from hydrogen gas productionChlorine forming a solid precipitate

Answer 1

Bubbles forming from hydrogen gas production

Step-by-step explanation

Given that;

`\text{ Zn}_((s))\text{ + 2HCl}_((aq))\rightarrow\text{ ZnCl}_(2(aq))\text{ + H}_(2(g))`

One of the method used in the preparation of hydrogen gas is the reaction of metals with acid

The above reaction is one of the method of producing hydrogen gas

When Zn reacts with HCl, bubbles formed which is as a result of hydrogen production.

Therefore, the correct answer is Bubbles forming from hydrogen gas production
