  2. Mixture - Wikipedia

    en.wikipedia.org/wiki/Mixture

    Air is an example of a solution as well: a homogeneous mixture of gaseous nitrogen solvent, in which oxygen and smaller amounts of other gaseous solutes are dissolved. Mixtures are not limited in either their number of substances or the amounts of those substances, though in most solutions, the solute-to-solvent proportion can only reach a ...

    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 ...

    Homogenization (from "homogeneous;" Greek, homogenes: homos, same + genos, kind) [5] is the process of converting two immiscible liquids (i.e. liquids that are not soluble, in all proportions, one in another) into an emulsion [6] (Mixture of two or more liquids that are generally immiscible).

  5. Ring-opening metathesis polymerisation - Wikipedia

    en.wikipedia.org/wiki/Ring-opening_metathesis...

    The mechanism of homogeneous ring-opening metathesis polymerization is well-studied. It is similar to any olefin metathesis reaction. Initiation occurs by forming an open coordination site on the catalyst. Propagation happens via a metallacycle intermediate formed after a 2+2 cycloaddition. When using a G3 catalyst, 2+2 cycloaddition is the ...

    Brass is an example of an alloy, being a homogeneous mixture of copper and zinc. Another example is steel, which is an alloy of iron with carbon and possibly other metals. The purpose of alloying is to produce desired properties in a metal that naturally lacks them. Brass, for example, is harder than copper and has a more gold-like color.

  7. Homogeneous catalysis - Wikipedia

    en.wikipedia.org/wiki/Homogeneous_catalysis

    The proton is a pervasive homogeneous catalyst [4] because water is the most common solvent. Water forms protons by the process of self-ionization of water. In an illustrative case, acids accelerate (catalyze) the hydrolysis of esters: CH 3 CO 2 CH 3 + H 2 O ⇌ CH 3 CO 2 H + CH 3 OH. At neutral pH, aqueous solutions of most esters do not ...

  9. Market structure - Wikipedia

    en.wikipedia.org/wiki/Market_structure

    Perfect competition refers to a type of market where there are many buyers and sellers that feature free barriers to entry, dealing with homogeneous products with no differentiation, where the price is fixed by the market. Individual firms are price takers [3] as the price is set by the industry as a whole. Example: Agricultural products which ...
