When heated iron wool is reacted with chlorine gas, it forms iron chloride.
In an experiment, 11.2 g of iron reacted exactly with 21.3 g of chlorine, Cl2\text{Cl}_2Cl2.
[relative atomic masses: Fe=56.0\text{Fe} = 56.0Fe=56.0, Cl=35.5\text{Cl} = 35.5Cl=35.5]
Determine, using this information, the balanced chemical equation for the reaction between iron and chlorine.
