Write the reaction equation for the oxidation of nitric oxide (II) to nitric oxide (IV). Does this reaction take place under normal conditions? What color do these oxides have? Why does the smoke emitted from the chimneys of some chemical plants turn yellow in the atmosphere? Environmentalists call these emissions “fox tails.”

2N0 + O2 = 2N02
This reaction takes place easily under ordinary conditions.
N0 – colorless gas
NO2 – red-brown gas
So NO2, a gas of red-brown color, then the yellow color of the smoke emitted from the pipes of some enterprises indicates the presence of poisonous gas NO2 in the emissions.
