Question

4nh3+5o2=4no+6h2o which substance is oxidized,reduced,and oxygen agent

Answer 1

4NH3 + 5O2 → 4NO + 6H2O

in NH3 , Oxidation state of N = -3
in NO , oxidation state of N = O
( NO is neutral compound )

hence, oxidation change of N -3 to 0

3 increment of oxidation no of N
so, N is oxidising . hence, NH3 is reducing agents

again ,
Oxidation state of O in O2 = 0
and Oxidation state of O in H2O = -2
hence, Oxidation no decreases of O -atoms
so, O2 is oxidising agents .

Answer 2

Answer:4NH3 is the substance oxidised

5O2 is the substance reduced.
