Detailed explanation-1: -A mixture is made when two or more substances are combined, but they are not combined chemically. There are two main categories of mixtures: homogeneous mixtures and heterogeneous mixtures. In a homogenous mixture all the substances are evenly distributed throughout the mixture (salt water, air, blood).

Detailed explanation-2: -A mixture in which two or more substances are evenly mixed, but not bonded together is a(n) homogeneous mixture, also called a(n) solution.

Detailed explanation-3: -9.1: Solutions-Homogeneous Mixtures. There are two types of mixtures: mixtures in which the substances are evenly mixed together (called a solution) and a mixture in which the substances are not evenly mixed (called a heterogeneous mixture). A solution is an even (or homogeneous) mixture of substances.

Detailed explanation-4: -A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample.

Detailed explanation-5: -Heterogenous Mixtures A heterogeneous mixture is a mixture of two or more chemical substances (elements or compounds) where the different components can be visually distinguished and easily separated by physical means. Examples include: mixtures of sand and water. mixtures of sand and iron filings.
