Question

what are solutions? a mixture of two or more solids that do not interact with each other. a gas that is mixed with another gas without any reaction. a special type of mixture where one substance is uniformly dissolved in a liquid. a type of solid that cannot dissolve in any liquid.

Explanation:

Solutions are homogeneous mixtures where one substance (solute) is uniformly dissolved in another (solvent), often a liquid - liquid or solid - liquid combination. The first option describes a simple mixture of solids, the second is just a gas - gas mixture, and the fourth describes an insoluble solid. The third option correctly defines a solution as a special type of mixture with uniform dissolution.

Answer:

A special type of mixture where one substance is uniformly dissolved in a liquid.
