Shape of hydrogen fluoride
WebbThe great reactivity of fluorine largely stems from the relatively low dissociation energy, a standard measure for bond energies, of the F―F bond (37.7 kilocalories per mole) and its ability to form stable strong bonds with essentially all the other elements. Fluorine (F2) and chlorine (Cl2) are gases at room temperature. Bromine (Br2) is a reddish-brown liquid at … WebbHydrogen fluoride is liberated from the mineral by the action of concentrated sulfuric acid: CaF 2 ( s ) + H 2 SO 4 → CaSO 4 (s) + 2 HF( g ) The resulting HF is converted into fluorine, fluorocarbons , and diverse …
