Tungsten hexafluoride was first obtained by conversion of tungsten hexachloride with hydrogen fluoride by Otto Ruff and Fritz Eisner in 1905. [11] [12] WCl 6 + 6 HF → WF 6 + 6 HCl. The compound is now commonly produced by the exothermic reaction of fluorine gas with tungsten powder at a temperature between 350 and 400 °C: [7] W + 3 F 2 → WF 6
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 .

In other words, for an object floating on a liquid surface (like a boat) or floating submerged in a fluid (like a submarine in water or dirigible in air) the weight of the displaced liquid equals the weight of the object. Thus, only in the special case of floating does the buoyant force acting on an object equal the objects weight.
Dissolved gas flotation (DGF) systems are used for a variety of applications throughout the world. The process floats solids, oils and other contaminants to the surface of liquids. The process floats solids, oils and other contaminants to the surface of liquids.
One person is dead, and five others are injured after a boat exploded in a Florida marina, according to reports. Around 6 p.m. on Monday, Dec. 23, fire rescue received calls about a boat explosion ...
Tungsten(V) fluoride is an inorganic compound with the formula WF 5. It is a hygroscopic yellow solid. Like most pentafluorides, it adopts a tetrameric structure, consisting of [WF 5] 4 molecules. In this way, each W center achieves octahedral coordination. [1]
