Expert Answer:

Combination chemical reactions are also called synthesis reactions. These reactions join two or more reactants into a product. The general equation is:

A + B ---> AB.

A combination reaction can be of three types:

a) Between two elements C + O2 ? CO2 Carbon completely burnt in oxygen yields carbon dioxide
b) Between two compounds 2CaO + 2H2O ? 2Ca(OH)2 Calcium oxide (lime) combined with water gives calcium hydroxide (slaked lime)
c) Between an element and a compound O2 + 2H2O ? 2H2O2 Oxygen (an element) combined with water (a compound) yields hydrogen peroxide
