(a)
Interpretation:
The reactant which is oxidized and the reactant which is reduced should be identified.
Concept Introduction:
The
Oxidation is the process in which either there is loss of electrons, oxidation number increases, or loss of hydrogen atoms takes place. An element is oxidized, when oxidation number increases.
Reduction is the process in which either there is gain of electrons, oxidation number decreases, or gain of hydrogen atoms takes place. An element is reduced, when oxidation number decreases.
(b)
Interpretation:
The oxidizing agent in the given chemical reaction should be determined.
Concept Introduction:
The chemical reaction in which both oxidation and reduction process takes place is known as redox reaction. In this reaction, transfer of electrons takes place among the elements.

(d)
Interpretation:
The balanced chemical equation for the given reaction should be written.

The chemical reaction in which both oxidation and reduction process takes place is known as redox reaction. In this reaction, transfer of electrons takes place among the elements.
Oxidation is the process in which either there is loss of electrons, oxidation number increases, or loss of hydrogen atoms takes place. An element is oxidized, when oxidation number increases.
Reduction is the process in which either there is gain of electrons, oxidation number decreases, or gain of hydrogen atoms takes place. An element is reduced, when oxidation number decreases.
A balanced reaction is a reaction in which number of atoms and charges should be equal on both reactant as well as on product sides.
