Question

Is a compound a homogeneous substance with definite composition.

• A. True
• B. False

Answer 1

The correct option is A True

Substances can be classsified into elements and compounds

Elements

• Substances which are made up of one kind of atoms
• Elements can not divide into smaller substances by simpler chemical processes
• Example: Oxygen $\left(\mathrm{O}\right)$, Carbon $\left(\mathrm{C}\right)$

Compounds

• Substances which are made up of different kind of atoms which are chemically combined in a fixed ratio.
• In the case of water i.e ${\mathrm{H}}_2\mathrm{O}$ where hydrogen and oxygen combine in the ratio 1:8.
• The atoms that actually constituting in the compound are in the same phase (homo means same), we can not differentiate the components present in it

Therefore, the given statement is true, i.e., a compound is a homogeneous substance with a definite composition.
