Interpretation:
Whether the street drug samples consist of a compound, element or mixture has to be determined.
Concept introduction:
An element can be defined as the simplest type of matter which is composed of only one kind of atom. Hence elements can be represented by symbols. Elements cannot be broken down into simpler substances by any chemical or physical means. Examples are carbon, hydrogen, oxygen, sulfur, chlorine etc.
Compounds are formed by the combination of two or more different elements in a fixed ratio via a
A mixture consists of a combination of two or more compounds or elements or compound and an element which are physically intermingled.
