Answer: Option (c) is correct answer.
Explanation:
The given reaction equation is as follows.
The number of atoms on reactant side are as follows.
- Fe = 2
- O = 3
- H = 1
- Cl = 1
The number of atoms on product side are as follows.
- Fe = 1
- O = 1
- H = 2
- Cl = 3
Therefore, in order to balance the equation we will balance the number of atoms in both reactant and product side.
Since number of Fe atoms in reactant side is 2, therefore, multiply by 2 in the product side.
Number of O atoms in reactant side is 3, therefore, multiply by 3 in the product side.
Now, the number of H atoms on product side is 6, therefore, multiply HCl by 6 in the reactant side.
The number of chlorine atoms on both reactant and product side equals 6.
Thus, the equation will become as follows.
Hence, the equation is balanced.
