Tungsten(VI) fluoride, also known as tungsten hexafluoride, is an inorganic compound with the formula W F 6. It is a toxic, corrosive, colorless gas, with a density of about 13 kg/m 3 (22 lb/cu yd) (roughly 11 times heavier than air). [2] [3] It is the densest known gas under standard ambient temperature and pressure (298 K, 1 atm). [4]
Tungsten(V) fluoride is an inorganic compound with the formula WF 5. It is a hygroscopic yellow solid. It is a hygroscopic yellow solid. Like most pentafluorides, it adopts a tetrameric structure, consisting of [WF 5 ] 4 molecules.
Tungsten tetrafluoride is an inorganic compound with the formula WF 4. This little studied solid has been invoked, together with tungsten pentafluoride , as an intermediate in the chemical vapor deposition of tungsten films using tungsten hexafluoride .
Tungsten fluoride may refer to: Tungsten tetrafluoride (tungsten(IV) fluoride) Tungsten pentafluoride (tungsten(V) fluoride) Tungsten hexafluoride (tungsten(VI) fluoride)
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Say you have a 4-year-old Labrador named Comet — with the new equation, Comet's real "dog age" would be slightly older than 53. The reason for the difference is actually pretty simple.
The reaction of tungsten(VI) oxytetrachloride and hydrogen fluoride will also produce WOF 4. [3] WOCl 4 + 4HF → WOF 4 + 4HCl. WOF 4 can also prepared by the reaction of lead(II) fluoride and tungsten trioxide at 700 °C. [3] 2PbF 2 + WO 3 → WOF 4 + 2PbO. Tungsten(VI) oxytetrafluoride hydrolyzes into tungstic acid. [1] [9] WOF 4 + 2 H 2 O ...
Oxygen's highest fluoride is oxygen difluoride, [89] but fluorine can theoretically (as of 2012) oxidize it to a uniquely high oxidation state of +4 in the fluorocation: OF + 3. [90] In addition, several chalcogen fluorides occur which have more than one chalcogen (O 2 F 2, [91] S 2 F 10, [92] etc.).
