Question

The equation Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g) is an example of which type of reaction?

Answer 1

Answer : This is an example of single-displacement reaction.

Explanation :

Single-displacement reaction : It is a type of reaction in which the more reactive metal displaces the least reactive metal from its solution.

It is represented as :

$A+BC\rightarrow AC+B$

where A is the most reactive metal and BC is the compound in which the B is the least reactive metal which is displaced by the most reactive metal A.

The given balanced reaction is,

$Mg(s)+2HCl(aq)\rightarrow MgCl_2(aq)+H_2(g)$

This reaction is an example of single-displacement reaction in which the magnesium metal displaces the hydrogen metal from its solution to give magnesium chloride and hydrogen gas as a product.

Hence, the given reaction is an example of single-displacement reaction.

Answer 2

Single-replacement reaction. hope it helped <3
