Which statement is true about solutions?
solutions are heterogeneous and can be physically separated.

solutions are mixtures that can be physically separated.

solutions are homogeneous and must be chemically separated.

solutions are made up of two substances that are chemically combined.

Solution are mixtures that can be physically separated

Explanation:

This is because we can separate solutions physically using some distinct separation techniques such as evaporation, simple distillation, distillation e.t.c

The answer is Solutions are mixtures that can be physically separated.

Explanation:

A solution is a homogeneous mixture at the molecular or ionic level of two or more pure substances that do not react with each other, whose components are in variable proportions. A chemical solution consists of a solvent and one or more solutes. The solute is the substance that dissolves and the solvent that dissolves it. the solutions can be separated by physical processes
