This is a physical combination of one substance dissolved in another.

Explanation:

A solution is a homogeneous mixture.

The solutions are characterized by uniform composition and one phase, but they can be either solid, liquid or gases.

In a solution there is, at least, one solute substance and one or more solvents.

A typical solution is salt and water: salt is the solute, which is dissolved, in water (the solvent).

In a solution, you can not distinguish visually the solute from the solvent, but, since they are physically, and not chemically, combined, they can be separated by physical media, e.g. evaporation.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
