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).
One other possible oxide that has not yet been synthesised is oxatetrazole (N 4 O), an aromatic ring. [15] Nitrous oxide (N 2 O), better known as laughing gas, is made by thermal decomposition of molten ammonium nitrate at 250 °C. This is a redox reaction and thus nitric oxide and nitrogen are also produced as byproducts.
In the NO − 3 anion, the oxidation state of the central nitrogen atom is V (+5). This corresponds to the highest possible oxidation number of nitrogen. Nitrate is a potentially powerful oxidizer as evidenced by its explosive behaviour at high temperature when it is detonated in ammonium nitrate (NH 4 NO 3), or black powder, ignited by the shock wave of a primary explosive.
Nickel(II) oxide is the chemical compound with the formula NiO. It is the principal oxide of nickel. [4] It is classified as a basic metal oxide. Several million kilograms are produced annually of varying quality, mainly as an intermediate in the production of nickel alloys. [5] The mineralogical form of NiO, bunsenite, is very rare.
Nitrogen oxide may refer to a binary compound of oxygen and nitrogen, ... Nitrogen trioxide (NO 3), or nitrate radical; Nitrous oxide (N 2 O), nitrogen(0,II) oxide;
One other possible oxide that has not yet been synthesised is oxatetrazole (N 4 O), an aromatic ring. [66] Nitrous oxide (N 2 O), better known as laughing gas, is made by thermal decomposition of molten ammonium nitrate at 250 °C. This is a redox reaction and thus nitric oxide and nitrogen are also produced as byproducts.
Instead, most laboratory syntheses stabilize and then heat the nitric acid to accelerate the decomposition. For example, the thermal decomposition of some metal nitrates generates NO 2: [14] Pb(NO 3) 2 → PbO + 2 NO 2 + 1 ⁄ 2 O 2. Alternatively, dehydration of nitric acid produces nitronium nitrate... 2 HNO 3 → N 2 O 5 + H 2 O 6 HNO 3 + 1 ...
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.
