WebPhosphine (PH₃) is a colorless, flammable, and explosive gas at room temperature that smells like garlic or decaying fish. Exposure to phosphine may cause, nausea, vomiting, stomach pain, diarrhea, thirst, muscle pain, difficulty breathing, and fluid in the lungs. Higher exposures and long-term exposure may cause serious harm. WebSep 15, 2024 · The recent (Sept. 2024) report of “Phosphine gas in the cloud decks of Venus” states that phosphine (PH 3) is only known to occur on Earth due to anaerobic life. …

WebPhosphine (PH 3 ) burns in oxygen gas to produce P 2 O 5 and water: 2 PH 3 ( g) + 4 O 2 ( g) → P 2 O 5 ( s) + 3 H 2 O (l) When 17.0 g PH 3 is mixed with 16.0 g O 2 : (a) Which is the limiting reactant? Phosphines are compounds that include PH3 and the organophosphines, which are derived from PH3 by substituting one or more hydrogen atoms with organic groups. [4] They have the general formula PH3−nRn. Phosphanes are saturated phosphorus hydrides of the form PnHn+2, such as triphosphane. [5] See more Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula PH3, classed as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly See more Philippe Gengembre (1764–1838), a student of Lavoisier, first obtained phosphine in 1783 by heating white phosphorus in … See more Phosphine may be prepared in a variety of ways.
