## Question:

A student conducts the following reaction:

{eq}Fe_3O_4 + 4 CO \rightarrow 3 Fe + 4CO_2 {/eq}.

If the student starts with 145 g {eq}Fe_3O_4 {/eq}, what is the percent yield of the reaction if only 38 liters of {eq}CO_2 {/eq} were produced?

## Iron (II,III) Oxide:

The molecule {eq}Fe_3O_4 {/eq} is called iron (II,III) oxide because one of the iron atoms has a +2 oxidation state and two of the iron atoms have a +3 oxidation state. It is sometimes written with the formula {eq}FeO \cdot Fe_2O_3 {/eq} and called ferrous ferric oxide.
