Dinitrogen trioxide (also known as nitrous anhydride) is the inorganic compound with the formula N 2 O 3.It is a nitrogen oxide.It forms upon mixing equal parts of nitric oxide and nitrogen dioxide and cooling the mixture below −21 °C (−6 °F): [4]
In atmospheric chemistry: NO x (or NOx) refers to the sum of NO and NO 2. [1] [2] NO y (or NOy) refers to the sum of NO x and all oxidized atmospheric odd-nitrogen species (e.g. the sum of NO x, HNO 3, HNO 2, etc.) NO z (or NOz) = NO y − NO x; Mixed Oxides of Nitrogen ("MON"): solutions of nitric oxide in dinitrogen tetroxide/nitrogen dioxide.
Dinitrogen oxide can potentially refer to any of at least four compounds: Dinitrogen monoxide (nitrous oxide), N 2 O; Dinitrogen dioxide, N 2 O 2, an unstable dimer of nitric oxide; Dinitrogen trioxide, N 2 O 3; Dinitrogen tetroxide, N 2 O 4; Dinitrogen pentoxide, N 2 O 5
The chemical element nitrogen is one of the most abundant elements in the universe and can form many compounds. It can take several oxidation states; but the most common oxidation states are -3 and +3. Nitrogen can form nitride and nitrate ions. It also forms a part of nitric acid and nitrate salts.
Chemical substance – Form of matter; List of alchemical substances; List of chemical elements; List of minerals – List of minerals with Wikipedia articles; List of named alloys; List of straight-chain alkanes; Polyatomic ion – Ion containing two or more atoms; Exotic molecule – a compound containing one or more exotic atoms
Cycloalkanes and aromatic compounds can be treated as the main parent chain of the compound, in which case the positions of substituents are numbered around the ring structure. For example, the three isomers of xylene CH 3 C 6 H 4 CH 3 , commonly the ortho- , meta- , and para- forms, are 1,2-dimethylbenzene, 1,3-dimethylbenzene, and 1,4 ...
Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...
Dinitrogen pentoxide (also known as nitrogen pentoxide or nitric anhydride) is the chemical compound with the formula N 2 O 5. It is one of the binary nitrogen oxides, a family of compounds that contain only nitrogen and oxygen. It exists as colourless crystals that sublime slightly above room temperature, yielding a colorless gas. [4]
