There are 5 different types of reaction that are in chemistry. Those 5 are single displacement, double displacement, synthesis, decomposition, and combustion. They are all both similar and different in ways. They are similar because they all are chemical reactions but they are different because they all do different things. Single displacement is a reaction in which a free atom becomes an ion and an ion becomes a free element. Double displacement is a reaction in which the positive ion of one compound replaces the positive ion of the other compound to produce two new compounds. Synthesis is two or more substances that are combined to produce a single, more complex substance. Decomposition is when a single substance is broken down into two or more simpler substances. Last but not least combustion is when a substance rapidly combines with oxegen to produce one or more oxides.

__BALANCING EQUATIONS!!__ 1. turn sentence into a chemical equation. 1a. figure out which chemicals are reactants and which are products. 2. Turn names into formulas. __Ionic__ __Covalent__ 1. write symbols just do what the name says 2. Figure out charge 3. Switcheroo 4. reduce

3. make a table under the equation and count atoms of each type. IF BALANCED **STOP** IF NOT YOU HAVE TO CHANGE THE COEFFICIENT. DO NOT CHANGE FORMULAS ONLY COEFFICIENTS. Ex. C6H12O6 + O2 ---> H2O + CO2 __6__ C __1__ ___12_ H__ 2 8 __O__ 3__

4. Finally if you have the same polyatomic and appear on both sides don't break it up!
