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.

[2] The company is headquartered at Kaiser Center, in Oakland, California.PG&E provides natural gas and electricity to 5.2 million households in the northern two-thirds of California, from Bakersfield and northern Santa Barbara County, almost to the Oregon and Nevada state lines.
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 ...
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.
