Write all the oxidation states of nitrogen. 

Give any two examples to show the negative oxidation state of nitrogen.

In nitric oxide (NO), the oxidation state of nitrogen is

Write different oxides of nitrogen. Mention the oxidation states of nitrogen in these oxides.

When NH_(4)NO_(3) is gently heated, an oxide of Nitrogen is formed. What is the oxidation state of Nitrogen in this oxide ?

One mole of N_(2)H_(4) ¸ loses 10 moles of electrons to form a new compound Z. Assuming that all the nitrogens appear in the new compound, what is the oxidation state of nitrogen in Z? (There is no change in the oxidation state of hydrogen.)

Write the oxidation state of the constituents in chromium hydride. Mention reasons.

The oxidation state of CrO_(3)

One mole of N_(2) H_(4) loses 10 moles of electrons to form a new compound X . Assuming that all the nitrogen appears in the new compound , the oxidation state of nitrogen in X is (there is no change in the oxidation number of hydrogen)
