Kinds of combination reaction?
Asked by Yusuf | 24 Mar, 2012, 09:50: AM
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 + B ---> AB.
A combination reaction can be of three types:
| Type | Example | |
|---|---|---|
| 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 |
