There are five basic types of chemical reactions: Synthesis, Combustion, Single Displacement, Double Displacement, and Decomposition. During SYNTHESIS, two or more substances combine to form a more complex substance. During COMBUSTION, a substance will rapidly combine with oxygen to form one of more oxides. During SINGLE DISPLACEMENT, a free atom will become an ion, and that ion will become a free element. During DOUBLE DISPLACEMENT, the positive ion of one compound will replace the positive ion of another compound to produce two new compounds. Finally, during DECOMPOSITION, a single substance will be broken down into two or more simpler substances.
