Look at the chemical reaction below.

Magnesium + hydrochloric acid → magnesium chloride + hydrogen

[tex]\[ \text{Mg} + 2\text{HCl} \rightarrow \text{MgCl}_2 + \text{H}_2 \][/tex]

In this reaction:

Magnesium (Mg) is a [tex]$\square$[/tex]
Hydrogen (H₂) is a [tex]$\square$[/tex]
Magnesium chloride (MgCl₂) is a [tex]$\square$[/tex]
Hydrochloric acid (HCl) is a [tex]$\square$[/tex]

In the chemical reaction:

[tex]\[ \text{Mg} + 2 \text{HCl} \rightarrow \text{MgCl}_2 + \text{H}_2 \][/tex]

We need to identify the roles of each substance—whether they are reactants or products. Let’s analyze the reaction step by step:

1. Magnesium (Mg):
- Magnesium (Mg) appears on the left side (before the arrow) of the reaction equation.
- Substances that are present before the reaction occurs are called reactants.
- Therefore, Magnesium (Mg) is a reactant.

2. Hydrogen (H[tex]\(_2\)[/tex]):
- Hydrogen (H[tex]\(_2\)[/tex]) appears on the right side (after the arrow) of the reaction equation.
- Substances that are produced as a result of the chemical reaction are called products.
- Therefore, Hydrogen (H[tex]\(_2\)[/tex]) is a product.

3. Magnesium chloride (MgCl[tex]\(_2\)[/tex]):
- Magnesium chloride (MgCl[tex]\(_2\)[/tex]) appears on the right side (after the arrow) of the reaction equation.
- Substances that are produced as a result of the chemical reaction are called products.
- Therefore, Magnesium chloride (MgCl[tex]\(_2\)[/tex]) is a product.

4. Hydrochloric acid (HCl):
- Hydrochloric acid (HCl) appears on the left side (before the arrow) of the reaction equation.
- Substances that are present before the reaction occurs are called reactants.
- Therefore, Hydrochloric acid (HCl) is a reactant.

To summarize, based on the chemical reaction given:

- Magnesium ([tex]\( \text{Mg} \)[/tex]) is a reactant.
- Hydrogen ([tex]\( \text{H}_2 \)[/tex]) is a product.
- Magnesium chloride ([tex]\( \text{MgCl}_2 \)[/tex]) is a product.
- Hydrochloric acid ([tex]\( \text{HCl} \)[/tex]) is a reactant.
