Explanation / Answer

7. Oxidising Agent is the reactant which itself gets reduced while oxidising other reactant.

Since oxidation is addition of oxygen and reduction is removal of oxygen,in the given reaction-

Ni changes to Ni(ClO4)2 so Ni is getting oxidized, and Ag goes from Ag(ClO4)2 to Ag

So, Ag is the oxidising Agent
