| Type of Reaction | Explanation | General Representation | Practice |
|---|---|---|---|
| Combination Reaction | Two or more compounds combine to form one compound. | A + B → AB | Practice Now |
| Decomposition reaction | The opposite of a combination reaction – a complex molecule breaks down to make simpler ones. | AB → A + B | Practice Now |
| Precipitation reaction | Two solutions of soluble salts are mixed resulting in an insoluble solid (precipitate) forming. | A + Soluble salt B → Precipitate + soluble salt C | Practice Now |
| Neutralization reaction | An acid and a base react with each other. Generally, the product of this reaction is a salt and water. | Acid + Base → Salt + Water | Practice Now |
| Combustion reaction | Oxygen combines with a compound to form carbon dioxide and water. These reactions are exothermic, meaning they give off heat. | A + O2 → H2O + CO2 | Practice Now |
| Displacement reaction | One element takes place with another element in the compound. | A + BC → AC + B | Practice Now |
