Question

For the reaction

NH4NO2(s) - heat - N2(g) + 2H2O(1)
Calculate the volume of nitrogen gas that would be produced at STP from 2.5g of the
dioxonitrate(iii) salt.​

Answer 1

Just as photosynthesis or chemosynthesis must reduce carbon dioxide in the atmosphere before it can be used in biological reactions, so must biological nitrogen change from elemental N 2 to a ‐3 level, as in ammonia, NH 3.
