Answer: Option (c) is the correct answer.
Explanation:
The given reaction is as follows.
[tex]Fe + Cl_{2} \rightarrow FeCl_{3}[/tex]
Number of atoms on reactant side are as follows.
Number of atoms on product side are as follows.
To balance the given equation, we multiply Fe by 2 and [tex]Cl_{2}[/tex] by 3 on the reactant side. Therefore, the balanced chemical equation will be as follows.
[tex]2Fe + 3Cl_{2} \rightarrow FeCl_{3}[/tex]
Thus, the coefficient of [tex]Cl_{2}[/tex] is 3.
In the given reaction, the coefficient of [tex]\bold{Cl_2}[/tex] is 3.
The correct option is (C) 3.
A number or amount associated with a variable is referred to as a coefficient.
In the given equation:
[tex]\bold{Fe +Cl_2 = FeCl_3}[/tex][tex]\bold{2Fe +3Cl_2 = 2FeCl_3}[/tex] →
Number of atoms of elements on the reactant side:
Fe = 1
Cl = 2
Number of atoms of elements on the product side:
Fe = 1
Cl = 3
To balance the equation, we put the given atomic number of the elements in the equation.
[tex]\bold{2Fe +3Cl_2 = 2FeCl_3}[/tex]
Thus, the coefficient for the chlorine is 3.
