Why would sand and water be an example of a heterogeneous mixture?

select all that apply.

chemical bonds are formed between the sand and water.
the mixture does not have a uniform appearance.
the mixture does not maintain a uniform composition.
the sand stays suspended in the water.

Sand and water be an example of a heterogeneous mixture because:-

Explanation:

A homogeneous mixture is a mixture in which solute particles are uniformly distributed throughout the solution. Whereas in a heterogeneous mixture particles of solute are not uniformly distributed throughout the solution.

For example, sand and water is a heterogeneous mixture because here sand particles are not uniformly distributed in the water. Hence, this mixture does not have uniform composition.

Also, after sometime the sand will deposit at the bottom of water, that is, sand will suspend in the water.
