Question

A compound is a chemical substance composed of two or more kinds of elements in a fixed ratio. By what means can the components of a compound be separated?

Answer 1

The answer is a chemical reaction

Step-by-step explanation:

Answer 2

Answer: Chemical reaction

Step-by-step explanation:

Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions.Example: Iron
`Fe`

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: water
`H_2O`

`2H_2O\rightarrow 2H_2+O_2`

Thus as can be seen from the reaction , the compound water can be separated into its constituent elements hydrogen and oxygen by decomposition reaction which is a chemical reaction.
