Question

HNO3 --------> H2O+N2O

Answer 1

4НNО3 = 4NО2 + 2Н2О + О2.

Answer 2

The chemical equation you provided represents the decomposition of nitric acid (HNO3) into water (H2O) and nitrous oxide (N2O) gas. This reaction can be written as follows:

2 HNO3 → H2O + 2 N2O

This reaction occurs when nitric acid is heated above a certain temperature, typically around 86 degrees Celsius. The reaction is endothermic, meaning that it requires energy to take place. As the nitric acid decomposes, it releases nitrous oxide gas and water vapor.

Nitric acid is commonly used in the production of fertilizers, explosives, and other chemicals. The decomposition reaction you provided is an important process in the manufacture of nitric acid, as it allows for the recovery of nitrous oxide gas, which can be used as an anesthetic or as a propellant in rockets.
