sf6 point group
Typical for a nonpolar gas, SF6 is poorly soluble in water but quite soluble in nonpolar organic solvents.

SF6 gas under pressure is used as an insulator in gas insulated switchgear (GIS) because it has a much higher dielectric strength than air or dry nitrogen. [7] It is inorganic, colorless, odorless, non-flammable, and non-toxic. It does not affect the vibrations of the vocal folds. Gas-insulated electrical gear is also more resistant to the effects of pollution and climate, as well as being more reliable in long-term operation because of its controlled operating environment. SF6 can be prepared from the elements through exposure of S8 to F2.

•Each symmetry point group has a particular designation. Sulfur hexafluoride was the tracer gas used in the first roadway air dispersion model calibration; this research program was sponsored by the U.S. Environmental Protection Agency and conducted in Sunnyvale, California on U.S. Highway 101.

S2F10 was considered a potential chemical warfare agent in World War II because it does not produce lacrimation or skin irritation, thus providing little warning of exposure.

SF6 is used in the electrical industry as a gaseous dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment, often replacing oil-filled circuit breakers (OCBs) that can contain harmful PCBs.

It is a hypervalent molecule.

The density of sulfur hexafluoride is relatively high at room temperature and pressure due to the gas's large molar mass. •Collections of symmetry operations constitute mathematical groups . SF6 gas under pressure is used as an insulator in gas insulated switchgear (GIS) because it has a much higher dielectric strength than air or dry nitrogen.

This application has been used to examine the vascularity of tumours. In this case, the centre of the molecule is the Sulfur atom. [9] It does not react with molten sodium below its boiling point,[10] but reacts exothermically with lithium. It is a hypervalent molecule. Sulfur hexafluoride is classified as a mild anesthetic. In general assignment of a character (irriducible representation) to a given molecular property depends on the molecular orientation. Sulfur hexafluoride microbubbles are administered in solution through injection into a peripheral vein. This behavior is described by the irreducible representation(irrep, character). Click the buttons labelled with Symmetry Operations below to view in 3D . [21] Arcing or corona can produce disulfur decafluoride (S2F10), a highly toxic gas, with toxicity similar to phosgene. [27] It remains visible in the blood for 3 to 8 minutes, and is exhaled by the lungs.[28].

Unlike helium, which has a molar mass of about 4 g/mol and pitches the voice up, SF6 has a molar mass of about 146 g/mol, and the speed of sound through the gas is about 134 m/s at room temperature, pitching the voice down. It is generally transported as a liquefied compressed gas. Some other sulfur fluorides are cogenerated, but these are removed by heating the mixture to disproportionate any S2F10 (which is highly toxic) and then scrubbing the product with NaOH to destroy remaining SF4. Therefore C. i. point group.

Unlike helium, which has a molar mass of about 4 g/mol and pitches the voice up, SF6 has a molar mass of about 146 g/mol, and the speed of sound through the gas is about 134 m/s at room temperature, pitching the voice down.
