Question

what is the difference between Heterogeneous and homogeneous?​

Answer 1

Answer:

HOMOGENEOUS MIXTURES

HETEROGENEOUS MIXTURES

The prefixes "homo"- indicate sameness The prefixes: "hetero"- indicate difference.

A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions.

A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.

Graphic on the left of "Dancing Raisins" shows liquid, solid, and gas substances in a heterogeneous mixture.

Particle size distinguishes homogeneous solutions from other heterogeneous mixtures. Solutions have particles which are the size of atoms or molecules - too small to be seen.

A colloid is a homogeneous solution with intermediate particle size between a solution and a suspension. Colloid particles may be seen in a beam of light such as dust in air in a "shaft" of sunlight. Milk, fog, and jello are examples of colloids.

In contrast a suspension is a heterogeneous mixture of larger particles. These particles are visible and will settle out on standing. Examples of suspensions are: fine sand or silt in water or tomato juice.

Corn oil is homogeneous, White vinegar is homogeneous. A sugar solution is homogeneous since only a colorless liquid is observed. Air with no clouds is homogeneous. For example beach sand is heterogeneous since you can see different colored particles. Vinegar and oil salad dressing is heterogeneous since two liquid layers are present, as well as solids. Air with clouds is heterogeneous, as the clouds contain tiny droplets of liquid water.

Answer 2

Answer:

Homogeneous mixture: A homogeneous mixture has a uniform composition and has only one phase. It can't be separated out physically. Example: A mixture of alcohol and water. Heterogeneous mixture: The heterogeneous mixture has a non-uniform composition and has two or more phases. It can be separated out physically.
