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).
In order to affirm the synthesis and isolation of N 4, this stream then underwent a second collision event, contacting a second target gas, O 2, reforming the N + 4 cation. [7] N 4 + O 2 → N + 4 + O − 2. The disappearance and reemergence of this "recovery peak" confirms the completion of both reactions, providing ample evidence for the ...
Vital statistics generally distinguish specific injuries and diseases as cause of death, from general categories like homicide, accident, and death by natural causes as manner of death. Both are listed in this category, as are both proximal and root causes of death. An injury that could be fatal is called major trauma; see also Category:Injuries.
The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
Antoine Lavoisier suggested instead the name azote, from the Ancient Greek: ἀζωτικός "no life", as it is an asphyxiant gas; this name is used in a number of languages, and appears in the English names of some nitrogen compounds such as hydrazine, azides and azo compounds.
Common names for ketones can be derived by naming the two alkyl or aryl groups bonded to the carbonyl group as separate words followed by the word ketone. Acetone; Acetophenone; Benzophenone; Ethyl isopropyl ketone; Diethyl ketone; The first three of the names shown above are still considered to be acceptable IUPAC names.
