NITROGEN DIOXIDE CAMEO Chemicals NOAA

Nitrogen Dioxide (nitrogen peroxide) is a strong oxidizing agent. Powdered aluminum burns in the vapor of carbon disulfide, sulfur dioxide, sulfur dichloride, nitrous oxide, nitric oxide, or nitrogen peroxide [Mellor 5:209-212. 1946-47]. Boron trichloride reacts energetically with nitrogen peroxide, phosphine, or fat and grease [Mellor 5:132

Nitrogen Dioxide Science On a Sphere

2010-5-1  Nitrogen dioxide (NO 2) is a key component of urban air pollution. The nitrogen oxides ("NOx" of which NO 2 is one component) are emitted from any combustion process. Coal- and gas-fired power plants and vehicles constitute the major anthropogenic (human-produced) sources. Forest fires and lightning are natural sources of NO 2, but globally it

NITRIC OXIDE AND NITROGEN DIOXIDE MIXTURE

NITRIC OXIDE AND NITROGEN DIOXIDE MIXTURE is an oxidizing gas. Supports the combustion of powdered aluminum [Mellor 5:209-212 1946-47]. The slow reaction between nitrogen dioxide and formaldehyde becomes explosive in the region of 180°C [Trans. Faraday Soc. 45:767-770. 1949].

NITROGEN TETROXIDE CAMEO Chemicals NOAA

Liquid NITROGEN TETROXIDE is an oxidizing agent consisting of an equilibrium mixture of colorless dinitrogen tetraoxide (N2O4) and red-brown nitrogen dioxide (NO2). The exact composition of the mixture depends on the temperature with higher temperature favoring conversion to NO2. Vaporizes readily to give NO2, also an oxidizing agent.
