what are heterogeneous mixtures
Answers
Answer:
Definition of Heterogeneous Mixtures
A mixture is a combination of two or more pure substances in which the original substances retain their chemical properties. In some mixtures, the initial substances cannot be detected after they have been mixed. In a heterogeneous mixture, the substances do not blend smoothly throughout, and the individual substances that compose the mixture can be detected. Heterogeneous mixtures can typically be separated back into their individual components through chemical or physical means.
Examples of Heterogeneous Mixtures
Scientists recognize two types of heterogeneous mixtures; they are known as suspensions and colloids. Suspensions are mixtures containing particles that settle out when left undisturbed. As a child, you may have played in the mud. If you take some muddy water and put it into a jar and leave it alone for a day or two, the mixture will settle out, and you will have the dirt on the bottom of the jar and the water on the top. This makes muddy water a heterogeneous mixture classified as a suspension. Suspensions such as this can typically be separated by using a filter and pouring the solution through the filter. This leaves the solid in the filter and the liquid in a container below the filter.

Answer:
This is a type of mixture in which all the components are completely mixed and all the particles can be seen under a microscope. We can easily identify the components and more than one phase can be seen by naked eyes.
Key points regarding this type of mixtures:
Particles are distributed non uniformly
We can judge a heterogeneous mixture by just seeing it
Non-uniform composition
Example: seawater, pizza, etc.
