In chemistry there are five main reaction types: decomposition, synthesis, single displacement, double displacement and combustion. Each reaction is characterized by the way the solution they form. Synthesis is a type of reaction when two or more elements or compounds react together to make one single compound or molecule. Decomposition is the same as synthesis, except backwards. Single displacement is when one element in a compound is exchanged for a different element. Double-displacement is similar to single-displacement except that two elements in a compound are replaced by two other elements. Combustion is when a substance combines with oxygen to produce a large amount of light and heat.
