Given the chemical reaction:
[tex]\[ \text{Magnesium} + \text{Hydrochloric acid} \rightarrow \text{Magnesium chloride} + \text{Hydrogen} \][/tex]
[tex]\[ Mg +2 HCl \rightarrow MgCl_2 + H_2 \][/tex]
we need to identify the roles of each substance in the reaction.
Step-by-step solution:
1. Identify the reactants and products:
The reaction starts with Magnesium (Mg) and Hydrochloric acid (HCl) as the substances on the left side of the reaction arrow. These are known as the reactants because they react with each other to form new substances.
[tex]\[ \text{Mg} \, (\text{Magnesium}), \, 2 \text{HCl} \, (\text{Hydrochloric acid}) \][/tex]
2. Determine the products formed:
The substances on the right side of the reaction arrow are the new substances formed as a result of the reaction. These are known as the products.
[tex]\[ \text{MgCl}_2 \, (\text{Magnesium chloride}), \, \text{H}_2 \, (\text{Hydrogen gas}) \][/tex]
3. Assign roles to each substance:
- Magnesium (Mg): This is a reactant, as it is one of the substances present at the start of the reaction.
- Hydrochloric acid (HCl): This is a reactant, as it also starts off on the left side and participates in the reaction.
- Magnesium chloride (MgCl2): This is a product, which is formed as a result of the reaction between magnesium and hydrochloric acid.
- Hydrogen (H2): This is a product, as it is produced in the reaction.
So, the detailed identification is as follows:
- Magnesium [tex]$( Mg )$[/tex] is a Reactant.
- Hydrogen [tex]$( H_2 )$[/tex] is a Product.
- Magnesium chloride [tex]$( MgCl_2 )$[/tex] is a Product.
- Hydrochloric acid [tex]$( HCl )$[/tex] is a Reactant.
Here is the filled-in version of the statement:
Magnesium [tex]$( Mg )$[/tex] is a Reactant. Hydrogen [tex]$( H _2 )$[/tex] is a Product. Magnesium chloride [tex]$( MgCl_2 )$[/tex] is a Product. Hydrochloric acid [tex]$( HCl )$[/tex] is a Reactant.
