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

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

Suppose 18.9 g of iron (Fe) is reacted with 29.3 g of oxygen (O2).

Select the limiting reagent.

Fe2O3

O2

Fe

Calculate the theoretical yield of iron(III) oxide (Fe2O3).

theoretical yield = g

The reaction produces 9.98 g of Fe2O3. What is the percent yield of the reaction?
