The PCL members of a province—i.e. the councilors of a province's component cities and municipalities—elect a president of their provincial chapter who will then serve as an ex officio member of their Sangguniang Panlalawigan (provincial legislature). [5] Councilors serve three-year terms, renewable twice consecutively. [6]

Although the text of the Constitution is easily accessible for free online, including a printable version via the National Archives and Records Administration, The New York Times reported in 2016 that, "pocket-size versions come with an added feature — a physical representation of Americans' rights that can be hoisted during a congressional hearing, political rally or a spirited discussion ...
PCl 5 ⇌ PCl + 4 + Cl −. At higher concentrations, a second equilibrium becomes more prevalent: 2 PCl 5 ⇌ PCl + 4 + PCl − 6. The cation PCl + 4 and the anion PCl − 6 are tetrahedral and octahedral, respectively. At one time, PCl 5 in solution was thought to form a dimeric structure, P 2 Cl 10, but this suggestion is not supported by ...
Phosphorus pentachloride, phosphorus pentabromide, and phosphorus heptabromide are ionic in the solid and liquid states; PCl 5 is formulated as PCl 4 + PCl 6 –, but in contrast, PBr 5 is formulated as PBr 4 + Br −, and PBr 7 is formulated as PBr 4 + Br 3 −. They are widely used as chlorinating and brominating agents in organic chemistry.
HP-GL, short for Hewlett-Packard Graphics Language and often written as HPGL, is a printer control language created by Hewlett-Packard (HP). HP-GL was the primary printer control language used by HP plotters. [1]
PCL 5 was released on the HP LaserJet III [2] in March 1990, adding Intellifont font scaling (developed by Compugraphic, now part of Agfa), outline fonts and HP-GL/2 (vector) graphics. PCL 5e (PCL 5 enhanced) was released on the HP LaserJet 4 [ 2 ] in October 1992 and added bi-directional communication between the printer and the PC and Windows ...
R 2 NH + PCl 3 + CH 2 O → (HO) 2 P(O)CH 2 NR 2 + 3 HCl. The herbicide glyphosate is also produced this way. The reaction of PCl 3 with Grignard reagents and organolithium reagents is a useful method for the preparation of organic phosphines with the formula R 3 P (sometimes called phosphanes) such as triphenylphosphine, Ph 3 P. 3 RMgBr + PCl ...
