Nitrogen dioxide - Wikipedia
One of several nitrogen oxides, nitrogen dioxide is a reddish-brown gas. It is a paramagnetic, bent molecule with C 2v point group symmetry. Industrially, NO2 is an intermediate in the synthesis of nitric acid, millions of tons of which are produced each year, primarily for the production of …
Basic Information about NO2 | US EPA
2024年7月16日 · EPA’s national and regional rules to reduce emissions of NO 2 and NO x will help state and local governments meet the National Ambient Air Quality Standard (NAAQS). EPA identifies areas where the air quality does not meet the national NO 2 standards.
Nitrogen Dioxide - American Lung Association
What Is Nitrogen Dioxide? Nitrogen dioxide, or NO 2, is a gaseous air pollutant composed of nitrogen and oxygen and is one of a group of related gases called nitrogen oxides, or NO x. Nitrogen dioxide forms when fossil fuels such as coal, oil, methane gas (natural gas) or diesel are burned at high temperatures.
Nitrogen Dioxide & Health - California Air Resources Board
What is nitrogen dioxide (NO 2)? Nitrogen Dioxide (NO 2) is a pungent gas that, along with fine airborne particulate matter, contributes to the reddish-brown haze characteristic of smoggy air in California. NO 2 is comprised of one atom of nitrogen and two atoms of oxygen, and is a gas at ambient temperatures.

nitrogen dioxide - Encyclopedia Britannica
2024年9月18日 · At low pressures or at high temperatures, NO 2 has a deep brown color, but at low temperatures the color almost completely disappears as NO 2 dimerizes to form dinitrogen tetroxide, N 2 O 4. At room temperature an equilibrium between the two molecules exists. 2NO 2 ⇌ N 2 O 4. Nitrogen dioxide reacts with water in one of two ways.
