Answer:

The oxidation number are

NH₃: -3

HNO₃ : +5

NO₂ : +4

Explanation:

The oxidation number is calculated considering that

a) oxidation number of hydrogen is +1 in all compounds except hydrides

b) oxidation number of oxygen is -2 in all compound except peroxides, superoxides and compound of fluorine.

a) NH₃ : let the oxidation number of nitrogen is "x"

x + 3 (+1) = 0

Therefore x = -3

b) HNO₃

Let the oxidation number of nitrogen is "x"

+1 + x +3(-2) = 0

x = -5.

c) NO₂

Let oxidation number of nitrogen ix "x"

x + 2(-2)= 0

x = +4
