Which set is an example of an element, a compound, and a mixture?

Element: Sulfur ; S

Compound: Water ; H2O

Mixture: Gunpowder ; 2 KNO3 + S + 3 C -> K2S + N2 + 3 CO2

Explanation:

An element is a pure substance that cannot be broken down into simpler substances. A periodic table for example has elements.

A compound is a chemical substance that's made of multiple elements held together by chemical bonds. All elements from the periodic table can be combined to make a compound but they have to bond a specific way in order for them to actually make something. Water is the easiest to remember.

A mixture is two or more substances that are physically combined. They are not chemically combined though. There are a few types of mixtures including homogeneous, heterogeneous, etc. Gunpowder is actually a mixture. It contains sulfur, carbon and potassium nitrate.
