What are compounds and mixtures primarily characterized as?

Pure substances
Combinations of matter
Elements
Reactions

The correct answer is: Combinations of matter

Compounds and mixtures are primarily characterized as combinations of matter because they consist of two or more different substances that are physically or chemically combined. A compound is formed when two or more elements chemically bond together, creating a substance with unique properties that differ from those of its individual components. A mixture, on the other hand, involves blending different substances, where each retains its original properties and can be separated by physical means. This distinction is fundamental in chemistry: while pure substances like elements and compounds have consistent properties and compositions, mixtures vary in composition and can be homogeneous or heterogeneous. Understanding this concept is essential for estheticians, particularly when dealing with ingredient formulations in skincare products, enabling them to make informed decisions about product interactions and effects on the skin.
