Mixtures.
heterogenous is not a word so there is none.
Heterogenous matter
heterogenous mixtures
Soil is a heterogeneous mixture because it is made up of various particles and components such as sand, clay, organic matter, water, and air. These components are not uniformly distributed throughout the soil, resulting in a non-uniform mixture.
it is a heterogenous mixture
It is neither heterogenous nor heterogenous. It is HOMOgenous
These can be different states of matter or immiscible materials.
Heterogenous state: (thick) liquid with (undissolved, very fine) solid particles.
homogeneous:composed of parts or elements that are all of the same kind: a homogeneous population.heterogeneous: different in kind; unlike; incongruous.
Gasoline is a homogeneous solution.
Heterogenous: there are at least two ingredients (possibly more because the Kool-Aid mix has several ingredients itself) that never quite mix completely. A homogenous solution would not have more than one, and no matter how vigorously you blend the Kool-Aid, it will tend to settle into its original ingredients as a heterogenous suspension.
Sodium chloride is a compound not a mixture.
