Detailed explanation-1: -A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers. Each of the layers is called a phase. In the case of vegetable soup, one phase would be the liquid soup itself.
Detailed explanation-2: -The statement that is true is heterogenous mixture are not pure substances. Explanation: A heterogenous mixture can simple be defined as a mixture that is not made up of uniform particles. As a heterogenous mixture is made up of different kinds of atoms, hence it is not a pure substance.
Detailed explanation-3: -A heterogeneous mixture is a mixture where throughout the solution the composition is not uniform. By definition, a single-phase consists of a pure substance or a homogeneous mixture. There are two or more phases of a heterogeneous mixture.
Detailed explanation-4: -A solution is a mixture of two or more substances in a single phase. At least two substances must be mixed in order to have a solution. Since solutions are mixtures, their compositions may vary over a very wide range.
