A decomposition reaction is one where a compound is broken down into its constituent chemical specieFor example:

2NaCl→2Na++Cl−2

The NaCl was broken down into the constituents Na+ and Cl−2

--(side note: the Cl is diatomic that explains the 2)


There are two types of replacement reactions, observe the differencesSingle Replacement: AB+C→AC+BDouble Replacement: AB+CD→AD+CB

Displacement reaction:

A chemical reaction in which an atom displaces another atoms from a compound.

1. Energy is not required in any form for this reaction.

2. Metals which are more reactive than hydrogen displace it form an acid.

3. Reactants are more than one.

Examples :

Mg + 2Hcl \:  -- \: - Mgcl2 + H2

Zn + 2Hcl \:  -  -  -  Zncl2 + H2

Decomposition reaction:

A chemical reaction in which a substance decomposes to form two or more simpler substances.

1. Energy is required in form of heat/light electricity.

2. Acid will not be decomposed.

3. Reactant is only one.

Examples:

CaCO3 -  -  \:  - CaO + CO2
