The chemistry of ANFO detonation is the reaction of ammonium nitrate with a long-chain alkane (C n H 2n+2) to form nitrogen, carbon dioxide, and water.In an ideal stoichiometrically balanced reaction, ANFO is composed of about 94.5% AN and 5.5% FO by weight.
An explosion is a type of spontaneous chemical reaction that, once initiated, is driven by both a large exothermic change (great release of heat) and a large positive entropy change (great quantities of gases are released) in going from reactants to products, thereby constituting a thermodynamically favorable process in addition to one that ...
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
Detonation cord will initiate most commercial high explosives (dynamite, gelignite, sensitised gels, etc.) but will not initiate less sensitive blasting agents like ANFO on its own. 25 to 50 grain/foot (5.3 to 10.6 g/m) detonation cord has approximately the same initiating power as a #8 blasting cap in every 2 to 4 inches (5 to 10 cm) along its ...
Which? bought and tested eight electric heaters costing as little as £7.20 from TikTok Shop and Temu, finding that six were unsafe. Heaters that ‘could explode, cause shock or start fires ...
During the Attack of Pearl Harbor, the USS Arizona was struck with an armor-piercing bomb which penetrated the upper deck and stopped inside the forward magazine. The bomb triggered an explosion which was powerful enough to cut the Arizona in half and is considered a sympathetic detonation as there was an apparent delay between the detonation of the bomb and the contents of the forward magazine.
