Mixture Mixture In chemistry, a mixture is a material made up of two or more different substances which are mixed. A mixture refers to the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids. Mixtures are one product of mechanically blending or mixing chemical substances such as elements and compounds, without chemical bonding or other chemical change, so that each ingredient substance retains its own chemical properties and makeup. Despite that there are no chemical changes to its constituents, the physical properties of a mixture, such
Mixture sample. This implies that "q" no longer depends on "i", and can therefore be replaced by the symbol "q". Gy's equation for the variance of the sampling error becomes: where "a" is that concentration of the property of interest in the population from which the sample is to be drawn and "M" is the mass of the population from which the sample is to be drawn.
