  2. Carbonation - Wikipedia

    en.wikipedia.org/wiki/Carbonation

    Carbonation is the chemical reaction of carbon dioxide to give carbonates, bicarbonates, and carbonic acid. [1] In chemistry, the term is sometimes used in place of carboxylation, which refers to the formation of carboxylic acids. In inorganic chemistry and geology, carbonation is common.

  3. Geochemistry of carbon - Wikipedia

    en.wikipedia.org/wiki/Geochemistry_of_carbon

    Carbon dioxide and carbonate are found where the oxygen fugacity is high. Lower oxygen fugacity results in diamond formation, first in eclogite, then peridotite, and lastly in fluid water mixtures. At even lower oxygen fugacity, methane is stable in contact with water, and even lower, metallic iron and nickel form along with carbides.

  4. Dry ice - Wikipedia

    en.wikipedia.org/wiki/Dry_ice

    Subliming dry ice pellet, with white frost on the surface. Dry ice colloquially means the solid form of carbon dioxide.It is commonly used for temporary refrigeration as CO 2 does not have a liquid state at normal atmospheric pressure and sublimes directly from the solid state to the gas state.

  5. Carbonated water - Wikipedia

    en.wikipedia.org/wiki/Carbonated_water

    Modern carbonated water is made by injecting pressurized carbon dioxide into water. [36] The pressure increases the solubility and allows more carbon dioxide to dissolve than would be possible under standard atmospheric pressure. When the bottle is opened, the pressure is released, allowing gas to exit the solution, forming the characteristic ...

  6. Weathering - Wikipedia

    en.wikipedia.org/wiki/Weathering

    Oxygen is also important, acting to oxidize many minerals, as is carbon dioxide, whose weathering reactions are described as carbonation. [ 22 ] The process of mountain block uplift is important in exposing new rock strata to the atmosphere and moisture, enabling important chemical weathering to occur; significant release occurs of Ca 2+ and ...

  7. Carboxylation - Wikipedia

    en.wikipedia.org/wiki/Carboxylation

    Carboxylation is a chemical reaction in which a carboxylic acid is produced by treating a substrate with carbon dioxide. [1] The opposite reaction is decarboxylation.In chemistry, the term carbonation is sometimes used synonymously with carboxylation, especially when applied to the reaction of carbanionic reagents with CO 2.

  8. Marine biogeochemical cycles - Wikipedia

    en.wikipedia.org/wiki/Marine_biogeochemical_cycles

    The Oceanic carbon cycle is a central process to the global carbon cycle and contains both inorganic carbon (carbon not associated with a living thing, such as carbon dioxide) and organic carbon (carbon that is, or has been, incorporated into a living thing). Part of the marine carbon cycle transforms carbon between non-living and living matter.

  9. Carbonization - Wikipedia

    en.wikipedia.org/wiki/Carbonization

    The gas produced by carbonization has a high content of carbon monoxide which is poisonous when breathed. Therefore, when working around the kiln or pit during operation and when the kiln is opened for unloading, care must be taken that proper ventilation is provided to allow the carbon monoxide, which is also produced during unloading through ...
