Question

The elements present in a compound can be separated by physical processes.

• A. True
• B. False

Answer 1

The correct option is B False

The elements in a compound can not be separated by a physical method.

• The elements in a compound are chemically combined and require a chemical or an electrochemical method to separate them.
• However, components of a mixture can be separated using physical methods.

Compound: A compound is a pure substance in which two or more elements combine chemically in a fixed composition.

• They can be broken down into elements that make up the compound by using chemical or electrochemical methods.
• Example: Water $\left({\mathrm{H}}_2\mathrm{O}\right)$ can be broken down by the method of electrolysis (i.e.; use of electricity to break down)

Mixture: When two or more substances (elements or compounds or an element and compound) are mixed in any proportion.

• The components of a mixture can be separated by physical methods of separation.
• Example: A mixture of Sand and Iron $\left(\mathrm{Fe}\right)$ can be separated by the use of a magnet (physical process) where Iron gets attracted to the magnet leaving behind sand.
