Answer: Option (c) is the correct answer.
Step-by-step explanation:
A reaction equation in which there are equal number of reactant and product molecules is known as a balanced equation.
For example,
Number of atoms on reactant side are as follows.
Al = 2
= 3
Cl = 6
Number of atoms on product side are as follows.
Al = 1
= 1
Cl = 3
Therefore, to balance this equation multiply
by 2 and
by 3 on product side.
Hence, the balanced chemical equation is as follows.
Thus, we can conclude that number of total chlorine atoms on product side are 6.
