  There are several types of chemical reactions such as combination, decomposition, displacement, oxidation and reduction. Combination reaction  In Combination reactions, two or more substances combine to form a single new substance. It is also known as synthesis reaction. Example: carbon combine with oxygen produces a single product namely carbondioxide. C + O 2   → CO 2   Decomposition reaction  In decomposition reaction, compound breaks down into two or more simpler substances. Example: Calcium carbonate on decomposition produces calcium oxide and carbon dioxide. CuCO 3 → CuO + CO 2   Displacement reaction when a more reactive element displaces a less reactive element from a compound, displacement reaction occurs. There are single and double displacement reactions.  Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s) In this reaction, iron has displaced another element, copper, from copper sulphate solution which is known as displac...
