Web15 hours ago · The molecular formula of phosphene is PH3 which indicates the compound has one phosphorous atom bonding with three hydrogen atoms. To understand the structure of PH3, we should know the electronic configuration of the atoms and how many valence electrons are there in the atoms. Phosphine upon contact with water at high pressure and temperature produces phosphoric acid and hydrogen: PH 3 + 4H 2 O H 3 PO 4 + 4H 2 Burning. Burning phosphine in the air produced phosphorus pentoxide (P 2 O 5) (which reacts with water to produce phosphoric acid): 2PH 3 + 4O 2 → P 2 O 5 + 3H … See more Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula PH3, classed as a pnictogen hydride.
