Which sample represents a homogeneous mixture? 1) c2h5oh(l) 2) c2h5oh(aq) 3) c2h5oh(g) 4) c2h5oh(s)

Option (2) 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, in an aqueous solution of ethanol there will be water and ethanol.

And as ethanol being an organic compound forms hydrogen bonding with water molecules due to which it dissolve in water and distributes evenly in water.

When 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, ethanol in water is a homogeneous mixture.

On the other hand, , and are all different states of ethanol.

Thus, we can conclude that sample represents a homogeneous mixture.
