Detailed explanation-1: -A compound is a substance that contains two or more elements chemically combined in a fixed proportion. The elements carbon and hydrogen combine to form many different compounds.

Detailed explanation-2: -In chemistry, a compound is a substance made up of two or more different chemical elements combined in a fixed ratio. When the elements come together, they react with each other and form chemical bonds that are difficult to break. These bonds form as a result of sharing or exchanging electrons between atoms.

Detailed explanation-3: -Compounds are pure substances that contain two or more elements combined in a definite fixed proportion. or Two or more elements combine together in a fixed proportion to form a compound.

Detailed explanation-4: -Compounds: A compound is a pure substance that is made up of two or more elements chemically combined in a fixed proportion by mass. Example: Water is represented as H 2 O in which hydrogen and oxygen are present in the fixed proportion of by mass i.e., the atomic mass of H = 1 u, O = 16 u .
