  • Sulfur hexafluoride - Wikipedia

    The density of sulfur hexafluoride is relatively high at room temperature and pressure due to the gaslarge molar mass. Unlike helium, which has a molar mass of about 4 g/mol and pitches the voice up, SF 6 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

  • Sulfur hexafluoride | F6S - PubChem

    Sulfur hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom. It is the most potent greenhouse gas currently known, with a global warming potential of 23,900 times that of CO2 over a 100 year period (SF6 has an estimated lifetime in the atmosphere of between 800 and 3,000 years).

  • Physiological Implications of Hydrogen Sulfide: A Whiff

    Apr 01, 2012 · At room temperature (20°C), one gram of H 2 S will dissolve in 242 ml H 2 O. Elevation of temperature increases H 2 S' solubility. Over time, H 2 S solution would turn cloudy due to the precipitation of elemental sulfur. This reflects the oxidation of H 2 S in the solution. H 2 S is a highly lipophilic molecule.
