Combination reactions occur when two or more substances combine to form a compound. There are three basic types of combination reactions. 1. Two elements react to form a new compound 2. An element and a compound react to form one new compound 3. Two compounds react to form one compound Element + Element Compound 1. Metal + Nonmetal Binary Ionic Compound Decomposition reactions occur when one compound decomposes to form: 1. Two elements 2. One or more elements and one or more compounds 3. Two or more compounds Displacement reactions occur when one element displaces another element from a compound. 1. These are redox reactions in which the more active metal displaces the less active metal or hydrogen from a compound in aqueous solution.

Unformatted text preview: • Metathesis reactions occur when two ionic aqueous solutions are mixed and the ions switch partners. AX + BY → AY + BX • Metathesis reactions remove ions from solution in two ways: 1. form predominantly unionized molecules like H 2 O 2. form an insoluble solid • Ion removal is the driving force of metathesis reactions. • Acid-Base (neutralization) Reactions 1. Formation of the nonelectrolyte H 2 O 2. acid + base → salt + water • Precipitation reactions are metathesis reactions in which an insoluble compound is formed. 1. The solid precipitates out of the solution much like rain or snow precipitates out of the air....
