Question

The balanced chemical equation, Zn (s) + 2 HCl (aq) ZnCl2 (aq) + H2 (g), can be expressed in words as: Answer Zirconium metal plus hydrogen chloride yields zirconium chloride solution and hydrogen gas Xenon solid plus hydrochloric acid yields xenon chloride and hydrogen gas Zinc metal plus hydrogen chloride yields zinc dichloride plus hydrogen gas Zinc metal plus an aqueous solution of hydrochloric acid yields an aqueous solution of zinc chloride plus hydrogen gas

Answer 1

Answer:

The correct answer is :

'Zinc metal plus an aqueous solution of hydrochloric acid yields an aqueous solution of zinc chloride plus hydrogen gas'.

Explanation:

Zn is the symbol of zinc metal

HCl is the molecular formula of hydrochloric acid

$ZnCl_2$ is the molecular formula of  Zinc chloride

$H_2$ molecular formula of hydrogen gas.

$Zn(s)+2 HCl(aq)\rightarrow ZnCl_2 (aq)+H_2 (g)$

In the given chemical reaction, 1 mole of zinc metal is reaction with 2 moles of hydrochloric acid to give 1 mole of zinc chloride solution and 1 mole of hydrogen gas.

Answer 2

choices are:

Zirconium metal plus hydrogen chloride yields zirconium chloride solution and hydrogen gas

Xenon solid plus hydrochloric acid yields xenon chloride and hydrogen gas

Zinc metal plus hydrogen chloride yields zinc dichloride plus hydrogen gas

Zinc metal plus an aqueous solution of hydrochloric acid yields an aqueous solution of zinc chloride plus hydrogen gas

right ans is:

Zinc metal plus an aqueous solution of hydrochloric acid yields an aqueous solution of zinc chloride plus hydrogen gas
