Step-by-step explanation:
A mixture is a substance that contains two or more components which are mixed together. In a mixture, components does not combine chemically with each other.
For example, coffee mixed in water is a mixture.
Whereas a compound is a substance in which two or more elements in similar composition are chemically combined to each other.
For example, HCl is a compound.
Thus, we can conclude that coffee is a solution of organic substances in water as is it a mixture.
