Effective concentration (activity) 1 mol/L for each aqueous or amalgamated (mercury-alloyed) species; Unit activity for each solvent and pure solid or liquid species; and; Absolute partial pressure 101.325 kPa (1.00000 atm; 1.01325 bar) for each gaseous reagent — the convention in most literature data but not the current standard state (100 kPa).
Mercury-Redstone 3, or Freedom 7, was the first United States human spaceflight, on May 5, 1961, piloted by astronaut Alan Shepard. It was the first crewed flight of Project Mercury . The project had the ultimate objective of putting an astronaut into orbit around the Earth and returning him safely.
2 ion, found in mercury(I) (mercurous) compounds. The existence of the metal–metal bond in Hg(I) compounds was established using X-ray studies in 1927 [2] [page needed] and Raman spectroscopy in 1934 [3] making it one of the earliest, if not the first, metal–metal covalent bonds to be characterised. Other mercury polycations are the linear ...
The Mercury Turnpike Cruiser is a series of automobiles that were produced by the Mercury division of Ford for the 1957 and 1958 model years. Named to commemorate the creation of the Interstate Highway System, the Turnpike Cruiser was marketed as the flagship Mercury model line, slotted above the Montclair when Mercury was positioned upmarket to luxury status when Edsel was introduced in 1958.
The National Advisory Committee for Aeronautics (NACA) was a United States federal agency that was founded on March 3, 1915, to undertake, promote, and institutionalize aeronautical research. [1]
Ethylmercury (sometimes ethyl mercury) is a cation composed of an organic CH 3 CH 2 — species (an ethyl group) bound to a mercury(II) centre, making it a type of organometallic cation, and giving it a chemical formula C 2 H 5 Hg +. The main source of ethylmercury is thimerosal. [1]
Iberia (modern Spain and Portugal) was possibly the Roman province richest in mineral ore, containing deposits of gold, silver, copper, tin, lead, iron, and mercury. [2] From its acquisition after the Second Punic War to the Fall of Rome, Iberia continued to produce a significant amount of Roman metals. [3] Britannia was also very rich in metals.
Lead azide is highly sensitive and usually handled and stored under water in insulated rubber containers. It will explode after a fall of around 150 mm (6 in) or in the presence of a static discharge of 7 millijoules. Its detonation velocity is around 5,180 m/s (17,000 ft/s). [12]
