P2O5 (or P4O10)
The common name of this compound is phosphorus pentaoxide and the systematic name is Potassium(V) Oxide.
Tetraphosphorous decoxide would be the formal IUAPC name, though P2O5 is the empirical formulation called phosphorous pentoxide, however it is improper to reduce covalent bonds.
The formula for phosphorus monochloride is PCl.
The formula for phosphorus pentachloride is PCl5.
The chemical formula for phosphorus acid is H3PO3.
phosphorus pentaoxide or p2o5 dimerises into p4o10
The common name of this compound is phosphorus pentaoxide and the systematic name is Potassium(V) Oxide.
It is phosphorus pentaoxide P2O5 which exists in dimeric form P4O10.
The chemical formula for diphosphorous pentaoxide is P2O5.
An oxide of phosphorus: diphosphorus pentaoxide
Tetraphosphorous decoxide would be the formal IUAPC name, though P2O5 is the empirical formulation called phosphorous pentoxide, however it is improper to reduce covalent bonds.
The formula for phosphorus pentachloride is PCl5.
The chemical formula for phosphorus mononitride is PN.
The formula for phosphorus monochloride is PCl.
Dihydrogen pentaoxide would mean 2 hydrogens and 5 oxygens, or H2O5. This would be an exceedingly unstable molecule, since two hydrogen atoms normally combine with only one oxygen atom, not five.
It is a chemical compound composed of phosphorus and oxygen, with molecular formula P4O10. It is produced by the complete combustion of phosphorus. It is also known as phosphorus pentaoxide (but the molecule is really composed of 4 phosphorus atoms and 10 oxygens).
