Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [ 1 ]
It has full lifetime guarantees for many of its products, such as hammers, screwdrivers and certain gauges. It also offers many limited lifetime guarantees and three-year guarantees on other products.
Free neutron decay. A schematic of the nucleus of an atom indicating. β−. radiation, the emission of a fast electron from the nucleus (the accompanying antineutrino is omitted). In the Rutherford model for the nucleus, red spheres were protons with positive charge and blue spheres were protons tightly bound to an electron with no net charge.
Anal/cloacal fin. The anal/cloacal fin is located on the ventral surface behind the anus / cloaca. The bones that support the anal fin are called pterygiophores. There are up to two series, a proximal series (axonosts) and a distal series (baseosts) Most fish use their anal fin to stabilize while swimming.
