The reddish-brown color is a consequence of preferential absorption of light in the blue region of the spectrum (400 – 500 nm), although the absorption extends throughout the visible (at shorter wavelengths) and into the infrared (at longer wavelengths). Learning to name chemical compounds requires that you: Determine the type of compound you are working with. At elevated temperatures nitrogen combines with oxygen to form nitric oxide: In the laboratory, NO2 can be prepared in a two-step procedure where dehydration of nitric acid produces dinitrogen pentoxide, which subsequently undergoes thermal decomposition: The thermal decomposition of some metal nitrates also affords NO2: Alternatively, reduction of concentrated nitric acid by metal (such as copper). This further exemplifies that NO2 toxicity is dangerous for children. It is one of several nitrogen oxides.
