Iron reacts with oxygen at high temperatures to form iron(III) oxide.

4Fe(s)+3O2(g)⟶2Fe2O3(s)4Fe(s)+3O2(g)⟶2Fe2O3(s)

Suppose 11.6 g11.6 g of iron (Fe)(Fe) is reacted with 20.4 g20.4 g of oxygen (O2).

Calculate the theoretical yield of iron(III) oxide (Fe2O3Fe2O3).

The reaction produces 5.32 g5.32 g of Fe2O3.Fe2O3. What is the percent yield of the reaction?
