Question

In which form of matter, the constituent elements are present in a fixed ratio?

Answer 1

Answer:

Compound:

• A pure substance constituted of two or more elements combined chemically in a fixed ratio is called a compound.
• It can be split into these simpler and different substances by chemical means.

For example, Common salt $\left(\mathrm{NaCl}\right)$:

Common salt is a compound made up of Sodium and chlorine atom.

These elements are combined chemically in a fixed ratio to form Common salt. We can not separate these components easily by physical means.

Conclusion:

A compound is a form of matter, in which the constituent elements are present in a fixed ratio.
