Answer:

Displacement reaction

Combination reaction

Double displacement reaction

Decomposition reaction

Double Displacement reaction

Explanation:

Types of Chemical Reactions

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
