1.    Displacement reaction between Zn and `H_2SO_4`

     `Zn + H_2SO_4 →ZnSO_4 + H_2`

2.    Reaction of photosynthesis

       `6CO_2+6H_2O\overset{sunlight}\underset{cholrophyll}{\rightarrow} C_6H_12O_6 +6O_2`

3.  Burning/combustion of natural gas

   `CH_4 + 2O_2 →CO_2 + 2H_2O + \text{energy}`

4.  Decomposition of Ferrous sulphate

  `2FeSO_4 → Fe_2O_3 + SO_2 + SO_3`

5.  Thermal decomposition of Lead nitrate

   `2PbNO_3→ 2PbO + 4NO_2 + O_2`

6.  Electrolysis of water

 `2H_2O \overset\text{electric current}{\rightarrow} 2H_2 + O_2`

7.   Double displacement reaction of Sodium sulphate with Barium chloride

  `Na_2SO_4 + BaCl_2 → BaSO_4 + 2NaCl`

8.   Rusting of Iron

  `4Fe   + 3O_2  +  n.H_2O → 2Fe_2O_3.nH_2O`

9.   Reaction of metal carbonate with an acid

 `Na_2CO_3 + 2HCl \rightarrow  2NaCl +H_2O + CO_2`

10.   Reaction of metal hydrogen carbonate with an acid

  `NaHCO_3 + HCl → NaCl + H_2O +CO_2`

11.  Formation of sodium hydroxide

  `2NaCl + 2H_2O → 2NaOH + H_2 + Cl_2`

12. Formation of bleaching powder

   `Ca(OH)_2  + Cl_2 \rightarrow CaOCl_2 + H_2O`

13. Formation of sodium zincate

  `2NaOH + Zn → Na_2ZnO_2 + H_2`

14.  Reaction of plaster of Paris with water

  `CaSO_4.frac{1}{2}H_2O + 1\frac{1}{2}H_2O →CaSO_4. 2H_2O`

15. Thermit reaction

   `Fe_2O3_ + 2Al → 2Fe + Al_2O_3 + heat`

16.  Combustion reaction

  `C+O_2 →CO_2   +  heat and light`

`CH_4 +O_2 →CO_2 + H_2O +  heat and light`

17.      Conversion of alcohol into acetic acid

`CH_3-CH_2OH \overset\text{alkaline KMnO4 +heat}\underset{acidic K_2Cr_2O_7+heat}{\rightarrow}CH_3COOH`

18.  Hydrogenation (formation of vegetable ghee)

`R_2C=CR_2  \overset{catalyst Ni}\underset{H_2}{\rightarrow} R_2HC- CHR_2`

19.  Dehydration of ethanol (ethyl alcohol)

`CH_3- CH_2OH \overset{hot & con.H_2SO_4}{\rightarrow} CH_2=CH_2 + H_2O`

20.  Formation of ester

`CH_3COOH + CH_3CH_2OH \overset{acid}{\rightarrow} CH_3COOCH_2CH_3 +H_2O`

21.  Saponification

  `CH_3COOC_2H_5 \overset{NaOH}{\rightarrow} C_2H_5OH + CH_3COONa`
