Answer:
Types of Chemical Reactions Explanation General Reaction
Combination reaction Two or more compounds combine to form one compound. A + B → AB
Decomposition reaction The opposite of a combination reaction – a complex molecule breaks down to make simpler ones. AB → A + B
Precipitation reaction Two solutions of soluble salts are mixed resulting in an insoluble solid (precipitate) forming. A + Soluble salt B → Precipitate + soluble salt C
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
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
Displacement reaction One element takes place with another element in the compound. A + BC → AC + B
