Chemical classification of matter is done on which basis?

Answer and explanation

Correct answer: Composition

The governing concept is that chemical classification depends on the composition and chemical identity of matter, not on its colour, size, or the speed of its particles. Matter is first considered as a pure substance or a mixture. A pure substance has a fixed composition and may be an element or a compound, whereas a mixture contains two or more substances whose proportions may vary. For example, oxygen is an element, water is a compound, and air is a mixture. Therefore, option C is correct. Particle motion and physical appearance can describe matter, but they do not determine its chemical classification.
