Nitric acid forms an oxide of nitrogen on reaction with $P_{4}O_{10}$. Write the reaction involved. Also,write the resonating structures of the oxide of nitrogen formed.

(N/A) The reaction between nitric acid $(HNO_{3})$ and phosphorus pentoxide $(P_{4}O_{10})$ is as follows:
$4 HNO_{3} + P_{4}O_{10} \rightarrow 2 N_{2}O_{5} + 4 HPO_{3}$
The oxide of nitrogen formed is dinitrogen pentoxide $(N_{2}O_{5})$. Its resonating structures are:
$[:O-N(=O)-O-N(=O)=O] \leftrightarrow [O=N(=O)-O-N(=O)-O:]$
