(a)
Interpretation: The given oxidation-reduction reaction needs to be balanced and the species undergoing oxidation and reduction needs to be identified.
Concept Introduction: By transfer of electrons,
(a)

Answer to Problem 46A
Balanced reaction is-
In this reaction, Fe is oxidized and O is reduced.
Explanation of Solution
The given reaction is as follows:
As number of Fe is one and O is 2 in reactant side and Fe is
Fe and
(b)
Interpretation: The given oxidation-reduction reaction needs to be balanced and the species undergoing oxidation and reduction needs to be identified.
Concept Introduction: By transfer of electrons, oxidation-reduction reactions are characterized. The transfer occurs to form ions. Oxidation reaction is caused by losing electrons and reduction is caused by gaining electrons.
(b)
