Answer 2

Step-by-step explanation:

Mixtures are the substances that contain two or more atoms mixed together in different composition.

There are two main classes of mixtures which are as follows.

Homogeneous mixtures - These are the mixtures in which solute particles are uniformly distributed into the solvent.

For example, NaCl when dissolved in water forms a homogeneous solution.

Heterogeneous mixture - These are the mixtures in which solute particles are non-uniformly distributed into the solvent.

For example, sand mixed in water is a heterogeneous solution.
