What is the oxidation state of nitric oxide?
The whole compound is seen to be neutral (0 oxidation state) as there are no ''-/+'' which indicate the overall charge of the compound. Although within almost all situations O has a -2 oxidation state. With this being now known and we know the whole compound is neutral (0) we can then see N must have the oxidation state of +2. 0 = (-2) + (+2)
When a dichromate ion acts as an oxidizing agent chromium's oxidation state drops from?
The dichromate ion is Cr2O72- and the chromium is in oxidation state 6. When it acts as an oxidizing agent it usually reduces from 6 to 3.2Cr2O72- -----> 4Cr3+ + 7O2 + 16e-See the related link for more information.

What is oxidation number of chromium in Cr2O7?
The oxidation number of chromium in Cr2O7 is +7. The oxidation number of oxygen is -2, so 7 O atoms times -2 = -14. In order to balance the -14 on the oxygen atom, each chromium atom must have an oxidation number of +7, because 2 Cr atoms times +7 equals +14.
