How are compounds broken down into their constituent elements?
Compounds can be broken down into their constituent elements by chemical changes. A chemical change (that is, a chemical reaction) is one in which the organization of the atoms is altered. An example of a chemical reaction is the burning of methane in the presence of molecular oxygen (O 2) to form carbon dioxide (CO 2) and water.
