When iron reacts with chlorine gas, 0.12 mol of iron (Fe\text{Fe}Fe) reacts completely with 0.18 mol of chlorine gas (Cl2\text{Cl}_2Cl2​).

Which is the correct balanced equation for this reaction?

A

Fe+Cl2→FeCl2\text{Fe} + \text{Cl}_2 \rightarrow \text{FeCl}_2Fe+Cl2​→FeCl2​

B

2Fe+3Cl2→2FeCl32\text{Fe} + 3\text{Cl}_2 \rightarrow 2\text{FeCl}_32Fe+3Cl2​→2FeCl3​

C

3Fe+2Cl2→Fe3Cl43\text{Fe} + 2\text{Cl}_2 \rightarrow \text{Fe}_3\text{Cl}_43Fe+2Cl2​→Fe3​Cl4​

D

2Fe+6Cl2→2FeCl62\text{Fe} + 6\text{Cl}_2 \rightarrow 2\text{FeCl}_62Fe+6Cl2​→2FeCl6​
