Answer: Option (c) is the correct answer.
Explanation:
A reaction equation in which there are equal number of reactant and product molecules is known as a balanced equation.
For example, [tex]Al_{2}(SO_{4})_{3} + 3Cl_{2} \rightarrow AlCl_{3} + SO_{4}[/tex]
Number of atoms on reactant side are as follows.
Al = 2
[tex]SO_{4}[/tex] = 3
Cl = 6
Number of atoms on product side are as follows.
Al = 1
[tex]SO_{4}[/tex] = 1
Cl = 3
Therefore, to balance this equation multiply [tex]AlCl_{3}[/tex] by 2 and [tex]SO_{4}[/tex] by 3 on product side.
Hence, the balanced chemical equation is as follows.
[tex]Al_{2}(SO_{4})_{3} + 3Cl_{2} \rightarrow 2AlCl_{3} + 3SO_{4}[/tex]
Thus, we can conclude that number of total chlorine atoms on product side are 6.
