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 ____
