Answer :
Law of conservation of mass : It states that the mass of reactant molecules must be equal to the mass of product molecules.
- The given unbalanced reaction is,
[tex]Mg+HCl\rightarrow H_2+MgCl_2[/tex]
First we have to balance the chemical reaction.
- The balanced chemical reaction is,
[tex]Mg+2HCl\rightarrow H_2+MgCl_2[/tex]
Now we have to calculate the mass of reactant side molecules and product side molecules.
Mass of reactants = [tex]Mg+2HCl=(24)+2(1+35.5)=97g[/tex]
Mass of products = [tex]H_2+MgCl_2=2(1)+(24+2(35.5))=97g[/tex]
From this we conclude that the mass of reactant is equal to the mass of product.
Answer:
Law of conservation of mass do not apply to this equation.
Explanation:
The law of conservation of mass states that the mass of objects/element before any reaction must be equal to the mass of objects/element after the reaction.
Here in this case –
Mg+HCL->H2+MgCl2
Mass of Mg before reaction = 1
Mass of H before reaction = 1
Mass of Cl before reaction = 1
Mass of Mg after reaction = 1
Mass of H after reaction = 2
Mass of Cl after reaction = 2
Thus it is clear that mass of H and Cl before and after the reaction is not equal and thus law of conservation of mass do not apply to this equation.
