Mixtures are classified as homogeneous and heterogeneous according to ___.

the distribution of their components

whether their components are elements or compounds

the masses of their components

the states of matter of ther components

Answer: Option (a) is the correct answer.

Explanation:

A mixture is defined as the substance that contains two or more different number of substances that are physically mixed together.

For example, a mixture of iron nails, sand and water.

A mixture in which solute particles are unevenly distributed into the solvent then it is known as a heterogeneous mixture.

For example, sand in water is a heterogeneous mixture.

A homogeneous mixture is defined as the mixture in which solute particles are evenly distributed in a solvent.

A homogeneous mixture is a clear solution.

For example, salt dissolved in water is a homogeneous mixture.

Thus, we can conclude that mixtures are classified as homogeneous and heterogeneous according to the distribution of their components.

whether their componets are made of elements or compounds

Explanation:

remeber homo means same and hetero mean different.

knowing this you also know that elements would be homogeneous and compounds would be heterogeneous since compunds are made of two or more things
