  3. Hydrothermal vent - Wikipedia

    en.wikipedia.org/wiki/Hydrothermal_vent

    Hydrothermal vent fluids harbor temperatures (~40 to >400 °C) well above that of ocean floor seawater (~4 °C), meaning that hydrothermal fluid is less dense than the surrounding seawater and will rise through the water column due to buoyancy, forming a hydrothermal plume; therefore, the phase during which hydrothermal plumes rise through the ...

  4. Hydrothermal vent microbial communities - Wikipedia

    en.wikipedia.org/wiki/Hydrothermal_vent...

    Deep ocean water contains the largest reservoir of nitrogen available to hydrothermal vents, with around 0.59 mM of dissolved nitrogen gas. [ 24 ] [ 25 ] Ammonium is the dominant species of dissolved inorganic nitrogen, and can be produced by water mass mixing below hydrothermal vents and discharged in vent fluids. [ 25 ]

    en.wikipedia.org/wiki/Chemosynthesis

    Venenivibrio stagnispumantis gains energy by oxidizing hydrogen gas.. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in ...

    Ocean: a major body of salty water that, in totality, covers about 71% of the Earth's surface. Oxbow lake: a U-shaped lake formed when a wide meander from the mainstem of a river is cut off to create a lake. Phytotelma: a small, discrete body of water held by some plants. Plunge pool: a depression at the base of a waterfall. Pool

  7. Ethane - Wikipedia

    en.wikipedia.org/wiki/Ethane

    Ethane (US: / ˈ ɛ θ eɪ n / ETH-ayn, UK: / ˈ iː θ eɪ n / EE-thayn) is a naturally occurring organic chemical compound with chemical formula C 2 H 6. At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by ...

  8. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    One or more of the hydrogen atoms can be replaced with other atoms, for example chlorine or another halogen: this is called a substitution reaction. An example is the conversion of methane to chloroform using a chlorination reaction. Halogenating a hydrocarbon produces something that is not a hydrocarbon. It is a very common and useful process.

  9. Catalytic reforming - Wikipedia

    en.wikipedia.org/wiki/Catalytic_reforming

    Catalytic reforming is a chemical process used to convert naphthas from crude oil into liquid products called reformates, which are premium "blending stocks" for high-octane gasoline. The process converts low-octane linear hydrocarbons (paraffins) into branched alkanes (isoparaffins) and cyclic naphthenes , which are then partially ...
