  2. Carbon - Wikipedia

    en.wikipedia.org/wiki/Carbon

    The most common oxidation state of carbon in inorganic compounds is +4, while +2 is found in carbon monoxide and transition metal carbonyl complexes. The largest sources of inorganic carbon are limestones, dolomites and carbon dioxide, but significant quantities occur in organic deposits of coal, peat, oil, and methane clathrates.

  3. Carbon compounds - Wikipedia

    en.wikipedia.org/wiki/Carbon_compounds

    Carbon compounds. Carbon compounds are defined as chemical substances containing carbon. [ 1][ 2] More compounds of carbon exist than any other chemical element except for hydrogen. Organic carbon compounds are far more numerous than inorganic carbon compounds. In general bonds of carbon with other elements are covalent bonds.

  4. Bicarbonate - Wikipedia

    en.wikipedia.org/wiki/Bicarbonate

    Bicarbonate. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). In inorganic chemistry, bicarbonate ( IUPAC -recommended nomenclature: hydrogencarbonate[ 2]) is an intermediate form in the deprotonation of carbonic acid. It is a polyatomic anion with the chemical formula H C O −.

  5. Carbon-based life - Wikipedia

    en.wikipedia.org/wiki/Carbon-based_life

    In a 2018 study, carbon was found to compose approximately 550 billion tons of all life on Earth. [ 16][ 17] It is the second most abundant element in the human body by mass (about 18.5%) after oxygen. [ 18] The most important characteristics of carbon as a basis for the chemistry of cellular life are that each carbon atom is capable of forming ...

  6. Carbonated water - Wikipedia

    en.wikipedia.org/wiki/Carbonated_water

    In 1767 Priestley discovered a method of infusing water with carbon dioxide by pouring water back and forth above a beer vat at a local brewery in Leeds, England. [30] [31] [32] The air blanketing the fermenting beer—called 'fixed air'—was known to kill mice suspended in it. Priestley found water thus treated had a pleasant taste, and he ...

  7. Composition of the human body - Wikipedia

    en.wikipedia.org/wiki/Composition_of_the_human_body

    The main elements that comprise the human body (including water) can be summarized as CHNOPS . About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium.

  8. Organic compound - Wikipedia

    en.wikipedia.org/wiki/Organic_compound

    The modern, commonly accepted definition of organic compound essentially amounts to any carbon-containing compound, excluding several classes of substances traditionally considered "inorganic". The list of substances so excluded varies from author to author. Still, it is generally agreed upon that there are (at least) a few carbon-containing ...

  9. Sodium carbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_carbonate

    Sodium carbonate decahydrate (Na 2 CO 3 ·10H 2 O), also known as washing soda, is the most common hydrate of sodium carbonate containing 10 molecules of water of crystallization. Soda ash is dissolved in water and crystallized to get washing soda. It is one of the few metal carbonates that is soluble in water.
