Here's why:
* Molecules are formed when two or more atoms bond together.
* Compounds are formed when two or more different elements chemically combine in a fixed ratio.
Therefore, a compound made of molecules is a compound where the basic unit is a molecule.
Examples of molecular compounds include:
* Water (H₂O): Two hydrogen atoms and one oxygen atom bond to form a water molecule.
* Carbon dioxide (CO₂): One carbon atom and two oxygen atoms bond to form a carbon dioxide molecule.
* Sugar (C₁₂H₂₂O₁₁): Twelve carbon atoms, twenty-two hydrogen atoms, and eleven oxygen atoms bond to form a sugar molecule.
