Question

HNO3 (+ KATALIZATOR) -- ??H2O+NO2+O2--??

Answer 1

Азотная кислота без катализатора разваливается, на свету: 4HNO3 = 4NO2 + 2H2O + O2.

Answer 2

HNO3 is the chemical formula for nitric acid. When a catalyst is added, it speeds up the reaction, but the specific catalyst is not mentioned in your question. However, in the presence of a catalyst, nitric acid can undergo decomposition to form water (H2O), nitrogen dioxide (NO2), and oxygen (O2). The balanced chemical equation for this reaction is:

2 HNO3 (aq) + catalyst → H2O (l) + 2 NO2 (g) + O2 (g)

In this reaction, the catalyst helps break down the nitric acid into its component molecules. Water, nitrogen dioxide, and oxygen are the products of this decomposition reaction.
