Sure, let's break down the chemical reaction to identify the role of each substance:
Given reaction:
[tex]\[ \text{Mg} + 2\text{HCl} \rightarrow \text{MgCl}_2 + \text{H}_2 \][/tex]
1. Magnesium ([tex]$\text{Mg}$[/tex]):
- Magnesium is on the left side of the reaction (before the arrow), which means it is one of the substances that starts the reaction.
- Substances that start the reaction are called reactants.
- Therefore, Magnesium ([tex]$\text{Mg}$[/tex]) is a reactant.
Filling the statement: "Magnesium [tex]$( \text{Mg} )$[/tex] is a reactant [tex]$\sim$[/tex]".
2. Hydrogen ([tex]$\text{H}_2$[/tex]):
- Hydrogen gas is on the right side of the reaction (after the arrow), which means it is one of the substances that is produced by the reaction.
- Substances that are produced by the reaction are called products.
- Therefore, Hydrogen ([tex]$\text{H}_2$[/tex]) is a product.
Filling the statement: "Hydrogen [tex]$\left( \text{H}_2 \right)$[/tex] is a [tex]$\square$[/tex] product [tex]$\square$[/tex]".
3. Magnesium chloride ([tex]$\text{MgCl}_2$[/tex]):
- Magnesium chloride is on the right side of the reaction (after the arrow), which means it is one of the substances that is produced by the reaction.
- Substances that are produced by the reaction are called products.
- Therefore, Magnesium chloride ([tex]$\text{MgCl}_2$[/tex]) is a product.
Filling the statement: "magnesium chloride [tex]$\left( \text{MgCl}_2 \right)$[/tex] is a [tex]$\square$[/tex] product [tex]$\square$[/tex]".
4. Hydrochloric acid ([tex]$\text{HCl}$[/tex]):
- Hydrochloric acid is on the left side of the reaction (before the arrow), which means it is one of the substances that starts the reaction.
- Substances that start the reaction are called reactants.
- Therefore, Hydrochloric acid ([tex]$\text{HCl}$[/tex]) is a reactant.
Filling the statement: "hydrochloric acid [tex]$( \text{HCl} )$[/tex] is a [tex]$\square$[/tex] reactant [tex]$\square$[/tex]".
Therefore, the completed statements are:
- Magnesium [tex]$( \text{Mg} )$[/tex] is a reactant [tex]$\sim$[/tex]
- Hydrogen [tex]$\left( \text{H}_2 \right)$[/tex] is a product [tex]$\square$[/tex]
- Magnesium chloride [tex]$\left( \text{MgCl}_2 \right)$[/tex] is a product [tex]$\square$[/tex]
- Hydrochloric acid [tex]$( \text{HCl} )$[/tex] is a reactant [tex]$\square$[/tex]
