  2. Nitrogen dioxide - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_dioxide

    Nitrogen dioxide is a chemical compound with the formula NO2. 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 ...

  3. Nitrogen oxide - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_oxide

    In atmospheric chemistry: NOx (or NO x) refers to the sum of NO and NO2. [1][2] NOy (or NO y) refers to the sum of NOx and all oxidized atmospheric odd-nitrogen species (e.g. the sum of NOx, HNO3, HNO2, etc.) NOz (or NO z) = NOy − NOx. Mixed Oxides of Nitrogen ("MON"): solutions of nitric oxide in dinitrogen tetroxide/nitrogen dioxide.

  4. Nitric oxide - Wikipedia

    en.wikipedia.org/wiki/Nitric_oxide

    Nitric oxide (nitrogen oxide or nitrogen monoxide [1]) is a colorless gas with the formula NO. It is one of the principal oxides of nitrogen . Nitric oxide is a free radical : it has an unpaired electron , which is sometimes denoted by a dot in its chemical formula ( • N=O or • NO).

  5. NOx - Wikipedia

    en.wikipedia.org/wiki/NOx

    In atmospheric chemistry, NOx is shorthand for nitric oxide (NO) and nitrogen dioxide (NO2), the nitrogen oxides that are most relevant for air pollution. [1][2] These gases contribute to the formation of smog and acid rain, as well as affecting tropospheric ozone. NOx gases are usually produced from the reaction between nitrogen and oxygen ...

  6. Nitrogen - Wikipedia

    en.wikipedia.org/wiki/Nitrogen

    Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bond to form N 2, a colourless and odourless diatomic ...

  7. Dinitrogen tetroxide - Wikipedia

    en.wikipedia.org/wiki/Dinitrogen_tetroxide

    Dinitrogen tetroxide, commonly referred to as nitrogen tetroxide (NTO), and occasionally (usually among ex-USSR/Russian rocket engineers) as amyl, is the chemical compound N 2 O 4. It is a useful reagent in chemical synthesis. It forms an equilibrium mixture with nitrogen dioxide. Its molar mass is 92.011 g/mol.

  8. Nitrous oxide - Wikipedia

    en.wikipedia.org/wiki/Nitrous_oxide

    Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas, nitrous, factitious air, among others, [4] is a chemical compound, an oxide of nitrogen with the formula N. 2O. At room temperature, it is a colourless non-flammable gas, and has a slightly sweet scent and taste. [4]

  9. Biological functions of nitric oxide - Wikipedia

    en.wikipedia.org/wiki/Biological_functions_of...

    Nitric oxide (nitrogen monoxide) is a molecule and chemical compound with chemical formula of N O. In mammals including humans, nitric oxide is a signaling molecule involved in several physiological and pathological processes. [1] It is a powerful vasodilator with a half-life of a few seconds in the blood.
