Question

Write balanced equation for the reaction between dilute Hydrochloric acid and Magnesium metal.

Answer 1

When dilute hydrochloric acid $\left(\mathrm{HCl}\right)$reacts with magnesium metal$\left(\mathrm{Mg}\right)$ then it produce magnesium chloride$\left({\mathrm{MgCl}}_2\right)$ and hydrogen gas $\left(H_2\right)$as a product.

Reaction between Magnesium metal and Hydrochloric acid:

$\underset{\mathrm{Magnesium}}{\underbrace{\mathrm{Mg}\left(\mathrm{s}\right)}}+\underset{\mathrm{Hydrochloric}\mathrm{acid}}{\underbrace{2\mathrm{HCl}\left(\mathrm{aq}\right)}}\to \underset{\mathrm{Magnesium}\mathrm{chloride}}{\underbrace{{\mathrm{MgCl}}_2\left(\mathrm{aq}\right)}}+\underset{\mathrm{Hydrogen}\mathrm{gas}}{\underbrace{{\mathrm{H}}_2\left(\mathrm{g}\right)}}$

This is an single replacement reaction
