=__Five Types of Chemical Reactions!__=

There are five main types of chemical reactions. They are Single Displacement, Double Displacement, Synthesis, Combustion, and Decomposition. During **single displacement** a free atom becomes an ion and an ion becomes a free element. In **double displacement** the positive ion of one compound replaces the positive ion of the other compound to produce two new compounds. During **synthesis** two or more substances are combined to to produce a single more complex substance. In **decomposition** a single substance is broken down into two or more simpler substances. During **combustion** a substance rapidly combines with oxygen to produce one or more oxides.
