Briannah reacts iron(III) oxide with carbon monoxide to form iron(II) oxide and carbon dioxide. Write and balance the equation showing this reaction.

Answer 1

Iron (III) means it has a +3 charge and oxygen always has a -2 charge, thus iron (III) oxide is written as Fe₂O₃.

Carbon monoxide is always written as CO.

Iron (II) means it has a +2 charge and oxygen always has a -2 charge, thus iron (II) oxide is written as FeO.

Finally, carbon dioxide is always written as CO₂.

Knowing this we can write the skeleton equation: Fe₂O₃ + CO -> FeO + CO₂ Now we just need to balance it to get the final answer:

Fe₂O₃ + CO -> 2FeO + CO₂
