  2. Nitrogen oxide - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_oxide

    Due to relatively weak N–O bonding, all nitrogen oxides are unstable with respect to N 2 and O 2, which is the principle behind the catalytic converter, and prevents the oxygen and nitrogen in the atmosphere from combusting.

  3. Nitrogen dioxide - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_dioxide

    Nitrogen dioxide is a chemical compound with the formula NO 2. One of several nitrogen oxides , nitrogen dioxide is a reddish-brown gas. It is a paramagnetic , bent molecule with C 2v point group symmetry .

  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).

    By contrast, the second three tree species, oak, beech and hickory, are associated with microbes that "absorb reactive nitrogen oxides," and thus can have a positive impact on the nitrogen oxide component of air quality. Nitrogen oxide release from forest soils is expected to be highest in Indiana, Illinois, Michigan, Kentucky and Ohio. [19]

    In a solid nitrogen matrix, nickel atoms combine with nitrogen molecules to yield Ni(N 2) 4. [1] Nickel phosphide Ni 2 P has density 7.33 and melts at 1100 °C. [4] The mineral Nickelskutterudite has formula NiAs 2-3, nickeline has formula NiAs and breithauptite has formula NiSb. NiAs melts at 967° and has density 7.77. NiSb melts at 1174°.

  7. Dinitrogen tetroxide - Wikipedia

    en.wikipedia.org/wiki/Dinitrogen_tetroxide

    Most of the water is condensed out, and the gases are further cooled; the nitric oxide that was produced is oxidized to nitrogen dioxide, which is then dimerized into nitrogen tetroxide: 2 NO + O 2 → 2 NO 2 2 NO 2 ⇌ N 2 O 4. and the remainder of the water is removed as nitric acid. The gas is essentially pure nitrogen dioxide, which is ...

  8. Dinitrogen dioxide - Wikipedia

    en.wikipedia.org/wiki/Dinitrogen_dioxide

    Dinitrogen dioxide is an inorganic compound having molecular formula N 2 O 2.Many structural isomers are possible. The covalent bonding pattern O=N–N=O (a non-cyclic dimer of nitric oxide (NO)) is predicted to be the most stable isomer based on ab initio calculations and is the only one that has been experimentally produced. [1]

  9. Oxide - Wikipedia

    en.wikipedia.org/wiki/Oxide

    An oxide (/ ˈ ɒ k s aɪ d /) is a chemical compound containing at least one oxygen atom and one other element [1] in its chemical formula. "Oxide" itself is the dianion (anion bearing a net charge of –2) of oxygen, an O 2– ion with oxygen in the oxidation state of −2. Most of the Earth's crust consists of oxides. Even materials ...
