Question

Why do mixtures show heterogeneous appearance?

Answer 1

Answer:

A homogeneous mixture is a solid, liquid or gaseous mixture that has the same proportions of its components throughout any given sample. Conversely, a heterogeneous mixture has components in which proportions vary throughout the sample. "Homogeneous" and "heterogeneous" are not absolute terms, but are dependent on context and the size of the sample. In chemistry, if the volume of a homogeneous suspension is divided in half, the same amount of material is suspended in both halves of the substance. An example of a homogeneous mixture is air.

Answer 2

 A heterogeneous mixture is a type of mixture that allows the components to be seen as two or more phases are present. A mixture is an example of water. Water is a homogeneous mixture of nitrogen, oxygen and smaller amounts of other compounds in the gaseous materials.
