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.
Part 1 :
The unbalanced chemical reaction is,
[tex]Cl_2+LiI\rightarrow LiCl+I_2[/tex]
In order to balance the chemical equation, the coefficient '2' put before the [tex]LiI[/tex] and [tex]LiCl[/tex] then we get the balanced chemical equation.
The balanced chemical reaction will be,
[tex]Cl_2+2LiI\rightarrow 2LiCl+I_2[/tex]
Part 2 :
The unbalanced chemical reaction is,
[tex]N_2+H_2\rightarrow NH_3[/tex]
In order to balance the chemical equation, the coefficient '3' put before the [tex]H_2[/tex] and the coefficient '2' put before the [tex]NH_3[/tex] then we get the balanced chemical equation.
The balanced chemical reaction will be,
[tex]N_2+3H_2\rightarrow 2NH_3[/tex]
Part 3 :
The unbalanced chemical reaction is,
[tex]Ca(OH)_2+HCl\rightarrow CaCl_2+H_2O[/tex]
In order to balance the chemical equation, the coefficient '2' put before the [tex]HCl[/tex] then we get the balanced chemical equation.
The balanced chemical reaction will be,
[tex]Ca(OH)_2+2HCl\rightarrow CaCl_2+H_2O[/tex]
Part 4 :
The unbalanced chemical reaction is,
[tex]Al(NO_3)_3+H_2SO_4\rightarrow Al_2(SO_4)_3+HNO_3[/tex]
In order to balance the chemical equation, the coefficient '2' put before the [tex]Al(NO_3)_3[/tex], the coefficient '3' put before the [tex]H_2SO_4[/tex] and the coefficient '6' put before the [tex]HNO_3[/tex] then we get the balanced chemical equation.
The balanced chemical reaction will be,
[tex]2Al(NO_3)_3+3H_2SO_4\rightarrow Al_2(SO_4)_3+6HNO_3[/tex]
Part 5 :
The unbalanced chemical reaction is,
[tex]C_4H_8+O_2\rightarrow CO_2+H_2O[/tex]
In order to balance the chemical equation, the coefficient '6' put before the [tex]O_2[/tex], the coefficient '4' put before the [tex]CO_2[/tex] and the coefficient '4' put before the [tex]H_2O[/tex] then we get the balanced chemical equation.
The balanced chemical reaction will be,
[tex]C_4H_8+6O_2\rightarrow 4CO_2+4H_2O[/tex]
Part 6 :
The unbalanced chemical reaction is,
[tex](NH_4)_2SO_4+KOH\rightarrow K_2SO_4+NH_3+H_2O[/tex]

Part 7 :
The unbalanced chemical reaction is,
[tex]C_2H_2+O_2\rightarrow CO_2+H_2O[/tex]
In order to balance the chemical equation,the coefficient '2' put before the [tex]C_2H_2[/tex], the coefficient '5' put before the [tex]O_2[/tex], the coefficient '4' put before the [tex]CO_2[/tex] and the coefficient '2' put before the [tex]H_2O[/tex] then we get the balanced chemical equation.
The balanced chemical reaction will be,
[tex]2C_2H_2+5O_2\rightarrow 4CO_2+2H_2O[/tex]
Part 8 :
The unbalanced chemical reaction is,
[tex]H_3PO_4+Mg(OH)_2\rightarrow Mg_3(PO_4)_2+H_2O[/tex]
