when two or more elements or compounds react so as to form one single compound, then the chemical reaction that takes place is called a combination reaction.

• | a)- Between elements | C + O2 → CO2 | Carbon completely burnt in oxygen yields carbon dioxide |-
• | b) Between compounds | CaO + H2O → Ca(OH)2 | Calcium oxide (lime) combined with water gives calcium hydroxide (slaked lime) |-
• | c) Between elements and compounds | 2CO + O2 → 2CO2 | Oxygen combines with carbon monoxide,And carbon dioxide is formed

A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B.

• Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

• The equation for this decomposition reaction is:
