  2. Mixture - Wikipedia

    en.wikipedia.org/wiki/Mixture

    It is an impure substance made up of 2 or more elements or compounds mechanically mixed together in any proportion. [1] A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions or colloids. [2] [3]

  3. Chemical reaction - Wikipedia

    en.wikipedia.org/wiki/Chemical_reaction

    In a synthesis reaction, two or more simple substances combine to form a more complex substance. These reactions are in the general form: A + B AB {\displaystyle {\ce {A + B->AB}}} Two or more reactants yielding one product is another way to identify a synthesis reaction.

    They are temporary attractive forces that form when the electrons in two adjacent atoms are positioned so that they create a temporary dipole. Additionally, London dispersion forces are responsible for condensing non polar substances to liquids, and to further freeze to a solid state dependent on how low the temperature of the environment is. [27]

  5. Chemical substance - Wikipedia

    en.wikipedia.org/wiki/Chemical_substance

    A chemical substance is a unique form of matter with constant chemical composition and characteristic properties. [1] [2] Chemical substances may take the form of a single element or chemical compounds. If two or more chemical substances can be combined without reacting, they may form a chemical mixture. [3]

  6. Miscibility - Wikipedia

    en.wikipedia.org/wiki/Miscibility

    Miscibility (/ ˌ m ɪ s ɪ ˈ b ɪ l ɪ t i /) is the property of two substances to mix in all proportions (that is, to fully dissolve in each other at any concentration), forming a homogeneous mixture (a solution). Such substances are said to be miscible (etymologically equivalent to the common term "mixable").

  7. Glossary of chemistry terms - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_chemistry_terms

    A molecular entity formed by loose association between two or more component molecular entities (ionic or uncharged), or the corresponding chemical species. The bonding between the components is normally weaker than in a covalent bond. [2] See also coordination complex. compound A substance that is made up of two or more chemically bonded elements.

  8. Molecule - Wikipedia

    en.wikipedia.org/wiki/Molecule

    A pure substance is composed of molecules with the same average geometrical structure. The chemical formula and the structure of a molecule are the two important factors that determine its properties, particularly its reactivity. Isomers share a chemical formula but normally have very different properties because of their different structures.
