Other general types of reactions include the combination reaction, the decomposition reaction, the displacement reaction, and the neutralization reaction.
1. A combination reaction is one in which two or more reactants combine to form a product.
2. Decomposition reactions are ones where a compound breaks down into two or more products.
3. In displacement reactions, an element in a reactant is replaced with another reactant. If one replacement occurs, the reaction is a single displacement. If two replacements occur, the reaction is a double displacement or metathesis reaction. Double displacements involve the switching of elements between two compounds such that two new compounds are formed. When the reactants in a double displacement reaction are an acid and a base, the reaction is a neutralization reaction. The products of a neutralization are a neutral salt and water.
