assign oxidation numbers to fe2O3 + 3CO -> 2Fe +3CO2. and identify the oxidants and reductants.?
回答 (3)
Fe2O3 + 3CO → 2Fe + 3CO₂
In Fe₂O₃ :
Oxidation number of Fe = +3
Oxidation number of O = -2
In CO :
Oxidation number of C = +2
Oxidation number of O = -2
In Fe :
Oxidation of number Fe = 0
In CO₂ :
Oxidation number of C = +4
Oxidation number of O = -2
Fe₂O₃ is the oxidant, as it is reduced.
This is because the oxidation number of Fe decreases from +3 to 0.
CO is the reductant, as it is oxidized.
This is because the oxidation number of C increases from +2 to +4.
Fe2O3 + 3CO ===> 2Fe + 3CO2
+3..-2......+2..-2.............0..........+4..-2
Fe is reduced/is the oxidizing agent
C is oxidized/is the reducing agent
