Final answer:
A mixture is a combination of substances that are not chemically bonded, while a compound is a pure substance made up of chemically bonded elements. Metal alloys are examples of mixtures while table salt is an example of a compound.
Step-by-step explanation:
A mixture is a combination of two or more substances that are not chemically bonded to one another and where no chemical reaction occurs between the substances. It is a heterogeneous mixture because its components are not uniformly distributed throughout the mixture. A metal alloy is an example of a mixture where different metals are combined.
On the other hand, a compound is a pure substance composed of atoms of two or more different elements that are chemically bonded to each other in a fixed ratio. Compounds can only be separated into their elements through chemical methods.
Example:
Table salt (NaCl) is a compound because it is made up of sodium and chlorine atoms that are chemically bonded together. Saltwater, however, is a mixture because salt and water are not chemically bonded and can be separated by physical means.
