Hydrazine is an inorganic compound with the chemical formula N 2 H 4.It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour.Hydrazine is highly hazardous unless handled in solution as, for example, hydrazine hydrate (N 2 H 4 ·xH 2 O).
Hydrazines (R 2 N−NR 2) are a class of chemical compounds with two nitrogen atoms linked via a covalent bond and which carry from one up to four alkyl or aryl substituents. . Hydrazines can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon grou

IUPAC states that, "As one of its major activities, IUPAC develops Recommendations to establish unambiguous, uniform, and consistent nomenclature and terminology for specific scientific fields, usually presented as: glossaries of terms for specific chemical disciplines; definitions of terms relating to a group of properties; nomenclature of chemical compounds and their classes; terminology ...
The most common use of monopropellants [3] is in low-impulse monopropellant rocket motors, [4] such as reaction control thrusters, the usual propellant being hydrazine [5] [6] which is generally decomposed by exposure to an iridium [7] [8] catalyst bed (the hydrazine is pre-heated to keep the reactant liquid).
The English name of element 74 is tungsten and not wolfram: the latter was once adopted by IUPAC (in 1949), but is no longer recommended by them (even as an alternative) per the 2011 Principles. (Of course, the symbol is still W, and the name "wolfram" may be referred to when explaining why that is the case, or when quoting text in languages ...
For example, the compound LiBr is made of Li + cations and Br − anions; thus, it is called lithium bromide. The compound BaO, which is composed of Ba 2+ cations and O 2− anions, is referred to as barium oxide. The oxidation state of each element is unambiguous. When these ions combine into a type-I binary compound, their equal-but-opposite ...
