(a)
Interpretation:
Given chemical equation has to be balanced and also the oxidizing agent and reducing agent has to be identified.
Concept Introduction:
In
In redox reactions, reducing agent is the one that gets oxidized by causing reduction. These agents can be ions, elements, or even compounds. In reduction, the oxidation number decreases due to gain of electrons.
