Note that the composition of a sports drink can vary — it could be made with somewhat more or less sugar, flavoring, or other components, and still be a sports drink. Other examples of homogeneous mixtures include air, maple syrup, gasoline, and a solution of salt in water. A mixture with a composition that varies from point to point is called a heterogeneous mixture. Italian dressing is an example of a heterogeneous mixture.
Its composition can vary because it may be prepared from varying amounts of oil, vinegar, and herbs. It is not the same from point to point throughout the mixture—one drop may be mostly vinegar, whereas a different drop may be mostly oil or herbs because the oil and vinegar separate and the herbs settle. Other examples of heterogeneous mixtures are chocolate chip cookies we can see the separate bits of chocolate, nuts, and cookie dough and granite we can see the quartz, mica, feldspar, and more.
Any mixture, whether homogeneous or heterogeneous, can be separated into pure components by physical means without changing the identities of the components. Although there are just over elements, tens of millions of chemical compounds result from different combinations of these elements.
Each compound has a specific composition and possesses definite chemical and physical properties that distinguish it from all other compounds. And, of course, there are innumerable ways to combine elements and compounds to form different mixtures.
