They always produce a single product.

They involve two or more reactants.

They can only occur with elements, not compounds.

They are also known as combination reactions.

2Na(s) + Cl2(g) → 2NaCl(s)

NaCl(s) → Na(s) + Cl2(g)

2NaCl(s) + O2(g) → 2Na2O(s) + Cl2(g)

Na(s) + Cl2(g) → NaCl2(s)

A reaction in which two elements combine to form a compound.

A reaction in which a single compound breaks down into two or more elements or new compounds.

A reaction in which two compounds exchange ions.

A reaction in which an element displaces another from a compound.

Aluminum

Aluminum displaces iron from iron(III) oxide because it is more reactive.

Iron displaces aluminum from aluminum oxide because it is more reactive.

Iron(III) oxide is reduced to iron by magnesium.

Aluminum is less reactive than iron.

It shows the number of molecules or atoms involved in the reaction.

It indicates the type of chemical reaction.

It represents the yield of the reaction.

It identifies the subscript in the formula.
