Phosphorus trifluoride (formula P F 3), is a colorless and odorless gas.It is highly toxic and reacts slowly with water. Its main use is as a ligand in metal complexes.As a ligand, it parallels carbon monoxide in metal carbonyls, [1] and indeed its toxicity is due to its binding with the iron in blood hemoglobin in a similar way to carbon monoxide.
Phosphorus trifluorodichloride is a chemical compound with the chemical formula PF 3 Cl 2.The covalent molecule trigonal bipyramidal molecular geometry.The central phosphorus atom has sp 3 d hybridization, and the molecule has an asymmetric charge distribution.
Phosphorus oxyfluoride is prepared by partial hydrolysis of phosphorus pentafluoride.. Phosphorus oxyfluoride is the progenitor of the simple fluorophosphoric acids by hydrolysis.
PGE Boiler #16 in 1988. The utility was founded in 1888 by Parker F. Morey and Edward L. Eastham as Willamette Falls Electric Company. On June 3, 1889, it sent power generated by one of four brush arc light dynamos at Willamette Falls over a 14-mile (23 km) electric power transmission line to Portland, the first US power plant to do so.
Pyrophosphoric acid. In chemistry, a phosphoric acid, in the general sense, is a phosphorus oxoacid in which each phosphorus (P) atom is in the oxidation state +5, and is bonded to four oxygen (O) atoms, one of them through a double bond, arranged as the corners of a tetrahedron.
The Pittsburgh Post-Gazette, also known simply as the PG, is the largest newspaper serving metropolitan Pittsburgh in the U.S. state of Pennsylvania.Descended from the Pittsburgh Gazette, established in 1786 as the first newspaper published west of the Allegheny Mountains, the paper formed under its present title in 1927 from the consolidation of the Pittsburgh Gazette Times and The Pittsburgh ...
In the 1950s the "Sun-Telly" was losing subscribers and advertisers to its direct competitor in the evening and Sunday fields, the Pittsburgh Press, and to a lesser degree the Post-Gazette. The Post-Gazette ' s co-publisher William Block Sr. later recalled that "The Press, which had a great deal of newer equipment, was in a position to give ...
Phosphorus pentafluoride is a Lewis acid.This property is relevant to its ready hydrolysis. A well studied adduct is PF 5 with pyridine.With primary and secondary amines, the adducts convert readily to dimeric amido-bridged derivatives with the formula [PF 4 (NR 2)] 2.
