Question

When the equation Fe +Cl2 FeCl3 → is balanced, what isthe coefficient for Cl2?

Answer 1

Answer: Option (c) is the correct answer.

Explanation:

The given reaction is as follows.

    $Fe + Cl_{2} \rightarrow FeCl_{3}$

Number of atoms on reactant side are as follows.

• Fe = 1
• Cl = 2

Number of atoms on product side are as follows.

• Fe = 1
• Cl = 3

To balance the given equation, we multiply Fe by 2 and $Cl_{2}$ by 3 on the reactant side. Therefore, the balanced chemical equation will be as follows.

           $2Fe + 3Cl_{2} \rightarrow FeCl_{3}$

Thus, the coefficient of $Cl_{2}$ is 3.

Answer 2

C.) Hence coefficient of Cl2 is 3.

Hope this helps, have a nice day!
