Answer : The balanced chemical reaction will be,
[tex]2LiNO_3+MgF_2\rightarrow 2LiF+Mg(NO_3)_2[/tex]
Explanation :
Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.
The unbalanced chemical reaction is,
[tex]LiNO_3+MgF_2\rightarrow LiF+Mg(NO_3)_2[/tex]
This reaction is an unbalanced chemical reaction because in this reaction number atoms are not balanced.
In order to balance the chemical equation, the coefficient '2' put before the [tex]LiNO_3[/tex] and [tex]LiF[/tex] then we get the balanced chemical equation.
The balanced chemical reaction will be,
[tex]2LiNO_3+MgF_2\rightarrow 2LiF+Mg(NO_3)_2[/tex]
