Copper nitrate is the oxidizing agent as it gets reduced from +2 to 0 oxidization state and oxidizes Fe from 0 to +2 state. This reaction is basically a reduction-oxidation (red-ox) reaction.
Fe + Cu(NO3)2 → Fe(NO3)2 + Cu what is the oxidizing agent?
The oxidizing agent is Cu(NO3)2.
What is the reducing agent of Fe+cu(No3)=Cu+Fc(No3)2
