[tex]\[ 2Fe + 3Cl_2 \rightarrow 2FeCl_3 \][/tex]
which of the following options gives the correct reactant:reactant ratio?

A. [tex]\[ Fe : Cl_2 = 1:1 \][/tex]
B. [tex]\[ Fe : Cl_2 = 2:3 \][/tex]
C. [tex]\[ Fe : Cl_2 = 3:2 \][/tex]
D. [tex]\[ Fe : FeCl_3 = 1:1 \][/tex]



Answer :

Let's analyze the given chemical reaction step-by-step and determine the correct reactant:reactant ratio.

The balanced chemical equation is:
[tex]\[ 2 Fe + 3 Cl_2 \rightarrow 2 FeCl_3 \][/tex]

This equation tells us that 2 moles of iron (Fe) react with 3 moles of chlorine gas (Cl_2) to produce 2 moles of iron(III) chloride (FeCl_3).

To determine the correct reactant:reactant ratio (Fe : Cl_2), we look at the coefficients of the reactants (Fe and Cl_2) in the balanced chemical equation. The coefficient for Fe is 2, and the coefficient for Cl_2 is 3.

Therefore, the mole ratio of Fe to Cl_2 is:
[tex]\[ Fe : Cl_2 = 2 : 3 \][/tex]

Thus, the correct reactant:reactant ratio is:
[tex]\[ Fe : Cl_2 = 2 : 3 \][/tex]

So the correct answer is:
[tex]\[ \boxed{Fe : Cl_2 = 2 : 3} \][/tex]
