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

4Fe(s)+3O2(g)⟶2Fe2O3(s)

Suppose 19.6 g of iron (Fe) is reacted with 19.6 g of oxygen (O2).

1.) Calculate the theoretical yield of iron(III) oxide ( Fe2O3 ).
2.) The reaction produces 6.47 g of Fe2O3. What is the percent yield of the reaction?
