The lighter noble gases xenon and krypton can be made to react with fluorine under special conditions, while argon will undergo chemical transformations only with hydrogen fluoride. [18] Nitrogen, with its very stable triple bonds, requires electric discharge and high temperatures to combine with fluorine directly. [19] Fluorine reacts with ...
Hydrogen fluoride is typically produced by the reaction between sulfuric acid and pure grades of the mineral fluorite: [14] CaF 2 + H 2 SO 4 → 2 HF + CaSO 4. About 20% of manufactured HF is a byproduct of fertilizer production, which generates hexafluorosilicic acid. This acid can be degraded to release HF thermally and by hydrolysis: H 2 SiF ...
The creation of sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. [2] Practical applications include the sparking mechanisms in lighters and various toys, using ferrocerium; starting fires without matches, using a firesteel; the flintlock mechanism in firearms; and spark testing ferrous metals.
Hydrofluorocarbons (HFCs), organic compounds that contain fluorine and hydrogen atoms, are the most common type of organofluorine compounds. They are commonly used in air conditioning and as refrigerants [5] in place of the older chlorofluorocarbons such as R-12 and hydrochlorofluorocarbons such as R-21.
This was historically used for reaction control systems, due to being easily storable. It is often used to drive Turbopumps, being used on the V2 rocket, and modern Soyuz. Hydrazine decomposes energetically to nitrogen, hydrogen, and ammonia (2N 2 H 4 → N 2 +H 2 +2NH 3) and is the most widely used in space vehicles. (Non-oxidized ammonia ...
Hydrogen and fluorine combine to yield hydrogen fluoride, in which discrete molecules form clusters by hydrogen bonding, resembling water more than hydrogen chloride. [ 126 ] [ 127 ] [ 128 ] It boils at a much higher temperature than heavier hydrogen halides and unlike them is miscible with water. [ 129 ]
The most common F-gases are hydrofluorocarbons (HFCs), which contain hydrogen, fluorine, and carbon. They are used in a multitude of applications including commercial refrigeration , industrial refrigeration, air-conditioning systems, heat pump equipment, and as blowing agents for foams, fire extinguishants, aerosol propellants, and solvents.
Cyanogen fluoride (molecular formula: FCN; IUPAC name: carbononitridic fluoride) is an inorganic linear compound which consists of a fluorine atom in a single bond with a carbon atom, and a nitrogen atom in a triple bond with the carbon atom. It is a toxic and explosive gas at room temperature.
