A …………….. can be broken into its elements by chemical means.

Answer 1

Compound:

• Two or more atoms combined chemically called compounds.
• In other words, can be broken into its elements by chemical means.
• The chemical transformation can break down substances into smaller compounds or their fundamental constituents.
• This chemical transformation sometimes necessitates the use of energy in the form of heat or electricity.
• Water $\left({\mathrm{H}}_2\mathrm{O}\right)$ is an example that contains hydrogen and oxygen.
• This can be separated by the electrolysis method.

Hence, A compound can be broken into its elements by chemical means.
