Within a blast furnace, iron(III) oxide is changed into iron, while carbon monoxide is changed into carbon dioxide. $\text{Fe}_2\text{O}_3 + 3\text{CO} \rightarrow 2\text{Fe} + 3\text{CO}_2$. What happens to each of these reactants?
- ABoth iron(III) oxide and carbon monoxide are oxidised.
- BBoth iron(III) oxide and carbon monoxide are reduced.
- CIron(III) oxide is oxidised and carbon monoxide is reduced.
- DIron(III) oxide is reduced and carbon monoxide is oxidised.
