Answer;
Oxidation number of O =-2 and N= +2
Explanation;
- The oxidation number of an atom is the charge that atom would have if the compound was composed of ions.
- NO is a gas whose oxidation number is zero.
- The oxidation number of oxygen is almost always -2
- Therefore to find the oxidation number of Nitrogen;
-2 + x = 0
x = +2
The oxidation number of N is + while that of O is -2
