Question

18. Say whether the following statements are true or false. Correct the false statements.

i. The constituent elements of a compound can be separated easily.

• A. True
• B. False

Answer 1

The correct option is B False

• A compound is defined as a pure substance that is made up of two or more elements in a fixed ratio by mass.
• For example, water $\left({\mathrm{H}}_2\mathrm{O}\right)$ is a compound that is formed when two atoms of hydrogen $\left(\mathrm{H}\right)$ combine with one atom of oxygen $\left(\mathrm{O}\right)$.
• The consistent elements of the compound cannot be separated easily because, in a compound, the constituent elements are bonded chemically.
• So, they can be separated only by chemical methods, not by physical methods.

Hence, the given statement is false.
