Give five example of decomposition reaction |
| Answer» Thermal decomposition reaction (Thermolysis)\tDecomposition of calcium carbonate:Calcium carbonate (lime stone) decomposes into calcium oxide (quick lime) and carbon dioxide when heated. Quick lime is the major constituent of cement.\t\tElectrolytic decomposition reaction (Electrolysis)Electrolytic decomposition may result when electric current is passed through an aqueous solution of a compound. A good example is the electrolysis of water.Photo decomposition reaction (Photolysis)\xa0\tDecomposition of silver chloride:Place a small quantity of silver chloride (AgCl) taken in a watch glass under sunlight for some time. The crystals slowly acquire a grey colour. On analysis, it is found that the sunlight has caused decomposition of silver chloride into silver and chlorine.\t\tDecomposition of hydrogen peroxide:\xa0In the presence of light, hydrogen peroxide decomposes into water and oxygen | |
