Homogeneous and heterogeneous mixtures settle, or separate. As a homogeneous mixture, a solution has one phase (liquid) although the solute and solvent can vary: for example, salt water. Air can be more specifically described as a gaseous solution (oxygen and other gases dissolved in the major component, nitrogen). Since interactions between molecules play almost no role, dilute gases form rather trivial solutions. In part of the literature, they are not even classified as solutions. In gas intermolecular space is greatest and intermolecular force of attraction is least. In chemistry, a mixture is a substance containing two or more elements or compounds that are not
Who is a Jew? in Jewish congregations. A person with one or two grandparents enrolled in a Jewish congregation could be classified as "Mischling", a crossbreed, of "mixed blood", if they were not a member of a Jewish congregation at the time the Nuremberg Laws were enacted.
