  2. Carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide

    Carbon dioxide is a chemical compound with the chemical formula CO 2.It is made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature and at normally-encountered concentrations it is odorless.

  3. Diatomic molecule - Wikipedia

    Otherwise, if a diatomic molecule consists of two different atoms, such as carbon monoxide (CO) or nitric oxide (NO), the molecule is said to be heteronuclear. The bond in a homonuclear diatomic molecule is non-polar. A periodic table showing the elements that exist as homonuclear diatomic molecules under typical laboratory conditions.

    The Gas composition of any gas can be characterised by listing the pure substances it contains, and stating for each substance its proportion of the gas mixture's molecule count.Nitrogen N 2 78.084 Oxygen O 2 20.9476 Argon Ar 0.934 Carbon Dioxide CO 2 0.0314

  5. Carbonyl group - Wikipedia

    en.wikipedia.org/wiki/Carbonyl_group

    Carbon dioxide. Other organic carbonyls are urea and the carbamates, the derivatives of acyl chlorides chloroformates and phosgene, carbonate esters, thioesters, lactones, lactams, hydroxamates, and isocyanates. Examples of inorganic carbonyl compounds are carbon dioxide and carbonyl sulfide. [citation needed]

  6. Chemical substance - Wikipedia

    en.wikipedia.org/wiki/Chemical_substance

    All compounds are substances, but not all substances are compounds. A chemical compound can be either atoms bonded together in molecules or crystals in which atoms, molecules or ions form a crystalline lattice. Compounds based primarily on carbon and hydrogen atoms are called organic compounds, and all others are called inorganic compounds.

    en.wikipedia.org/wiki/Homogeneity_and_heterogeneity

    Homogeneity and heterogeneity; only ' b ' is homogeneous Homogeneity and heterogeneity are concepts relating to the uniformity of a substance, process or image.A homogeneous feature is uniform in composition or character (i.e. color, shape, size, weight, height, distribution, texture, language, income, disease, temperature, radioactivity, architectural design, etc.); one that is heterogeneous ...

  8. Oxocarbon - Wikipedia

    en.wikipedia.org/wiki/Oxocarbon

    In chemistry, an oxocarbon or oxide of carbon is a chemical compound consisting only of carbon and oxygen. [ 1 ] [ 2 ] The simplest and most common oxocarbons are carbon monoxide (CO) and carbon dioxide ( CO 2 ).

  9. Carbon compounds - Wikipedia

    en.wikipedia.org/wiki/Carbon_compounds

    Organic carbon compounds are far more numerous than inorganic carbon compounds. In general bonds of carbon with other elements are covalent bonds. Carbon is tetravalent but carbon free radicals and carbenes occur as short-lived intermediates. Ions of carbon are carbocations and carbanions are also short-lived. An important carbon property is ...
