What is the oxidation state of nitrogen in HNO3?

Answer 1

This is a perfect example of why we have to be so careful about which letters are upper case and which are lower. No stands for nobelium, but as you have also written cl, which should be Cl, I suspect you don't mean nobelium chloride, but NOCl, nitrosyl chloride. If it were NoCl, then the N alone would be meaningless, and the nobelium would have an oxidation state of +1. In NOCl, the nitrogen has an oxidation state of +3.

Answer 2

The oxidation state on N would be 3- since the subscript on the Cl atom is 3 and is (-) because it has the stronger ionization energy compared to the Cl atom.

Answer 3

I think it's 0

Answer 4

+5 oxidation state

Answer 5

-3 oxidation state

Answer 6

-1 oxidation state

Answer 7

Nitrogen is here trivalent.

Answer 8

It will be+3

You have to believe it as the answer is given by me

Answer 9

2

Answer 10

+1
