Interpretation: The oxidation number of N in nitrate, nitrite, NO, N2O and N2 needs to be determined.
Concept introduction: The oxidation state of an atom is zero in a neutral substance that contains atoms of just one component. The oxidation state of straightforward ions is adequate for the charge on the ion.
Answer to Problem 1P
The oxidation numbers of N in nitrate, nitrite, NO, N2O and N2 is +5, +3, +2, +1 and 0 respectively.
Explanation of Solution
The most stable oxidation state of oxygen is zero.
The formula of the nitrate is
The oxidation state of N in nitrate can be calculated as follows:
The formula of the nitrite is
The oxidation state of N in nitrite can be calculated as follows:
For NO, the charge on the overall molecule is zero thus,
For N2O , the charge is also zero.
N2also has zero charge thus,

- Triosephosphate isomerase (TIM) catalyzes the conversion of dihydroxyacetone phosphate to glyceraldehyde-3-phosphate. The enzyme’s catalytic groups are Glu 165 and His 95. In the first step of the reaction, these catalytic groups function as a general-base and a general-acid catalyst, respectively.
