a. Write the balanced reaction between iron (III) oxide and carbon monoxide to form iron metal and carbon dioxide.

iron (III) oxide →  Fe3O2 
carbon monoxide → CO
iron metal → Fe
carbon dioxide → CO2

Balanced reaction: Fe2O3 + 3 CO → 2 Fe + 3 CO2


b. Identify the oxidation state of:

A. iron in iron (III) oxide ____

iron (III) oxide →  Fe2O3 

This is neither a peroxide nor superoxide, which means O.S. of O = –2

This is also a neutral compound so the total oxidation state is zero.

2 (O.S. of Fe) + 3(O.S. of O) = 0
2 (O.S. of Fe) + 3(–2) = 0
2 (O.S. of Fe) – 6 = 0
2 (O.S. of Fe) = +6
O.S. of Fe = +3

Oxidation State of Fe = +3


B. carbon in carbon monoxide ____
