undefined The reactions of magnesium and aluminum with hydrochloric acid can be represented by the following chemical equations:

1. Reaction of magnesium (Mg) with hydrochloric acid (HCl):

$$ \text{Mg} + 2\text{HCl} \rightarrow \text{MgCl}_2 + \text{H}_2 $$

2. Reaction of aluminum (Al) with hydrochloric acid (HCl):

$$ 2\text{Al} + 6\text{HCl} \rightarrow 2\text{AlCl}_3 + 3\text{H}_2 $$

Ellie Andrews · Answer

undefined The equations for the reactions of magnesium and aluminum with hydrochloric acid are as follows:

1. Magnesium:
   $ \text{Magnesium} + 2\text{HCl} \rightarrow \text{Magnesium chloride} + \text{Hydrogen gas} $
   $ \text{Mg} + 2\text{HCl} \rightarrow \text{MgCl}_2 + \text{H}_2 $

2. Aluminum:
   $ \text{Aluminum} + 6\text{HCl} \rightarrow \text{Aluminum chloride} + 3\text{Hydrogen gas} $
   $ \text{2Al} + 6\text{HCl} \rightarrow \text{2AlCl}_3 + \text{3H}_2 $

In these reactions, magnesium displaces hydrogen from hydrochloric acid to form magnesium chloride and hydrogen gas, while aluminum reacts with hydrochloric acid to produce aluminum chloride and hydrogen gas.
