Further explanation

Given

Reaction

Mg(s) + 2 HCl(aq) → MgCl2 (aq) + H2 (g)

Required

Type of reaction

Solution

A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds

General formula :

A + BC ⇒ AC + B

Not all of these reactions can occur. We can use the activity series(the Volta series)

The more left the position of a metal in the series, the more reactive metal (easy to release electrons, the stronger the reductor)
