The oxidation number of reactant Fe is 0 while the oxidation number of iron in the product is +3
What s a redox reaction?
The term redox reaction implies a reaction in which there is an increase in the oxidation number of a specie and the decrease in the oxidation number of another specie.
Now we have the answers as follows;
1) The oxidation number of reactant Fe is 0
2) The oxidation number of reactant oxygen is 0
3) The oxidation number of iron in the product is +3
4) The oxidation number of oxygen in the product is -2
5). Iron is oxidized in the reaction
6) Oxygen is reduced in the reaction
7) The oxidizing agent in this case is the oxygen atom
