Identify the substance oxidized reduced, oxidizing agent and a reducing agent for each of the following reactions:

N₂H₄ (l) + 2H₂O₂ (l) → N₂(g) + 4H₂O(l)

Oxidised substance:- N₂H₄

Reduced Substance:- H₂O₂

Reducing agent:- N₂H₄

Oxidising agent:- H₂O₂

Explanation:- Oxidising agent is a reagent which can increase the O.N. of an element in a given substance.

H₂O₂ helps nitrogen to increase its Oxidation state.

The reduced substance is a reagent whose oxidation state has been decreased.

Here in this case, O in H₂O₂ has -1 oxidation state and the O.N. is reduced to -2 as oxygen in the product side is present in -2 O.N.

The oxidised substance is a reagent whose oxidation state has been decreased.

N in N₂H₄ is present in -2 O.N which is increased to zero in the product side where N is present as N₂ (its elemental form)

Reducing Agent is a reagent which lowers the oxidation number of an element in a given substance.

N₂H₄ helps oxygen to decrease its O.N.
