(a)
Interpretation:
The following skeleton reaction has to be balanced and the oxidizing and reducing agents has to be identified.
Concept Introduction:
Oxidizing agent:
A compound or group that causes the oxidation in another compound or group is said to be an oxidizing agent. Most common oxidizing agents are oxygen, hydrogen peroxide and halogens.
Reducing agent:
A compound or group that causes the reduction in another compound or group is said to be a reducing agent.
Oxidation:
A reaction in which a compound gains electrons is said to be oxidation.
Reduction:
A reaction in which a compound loses electrons is said to be reduction.
