Question

10 example of decomposition reaction​

Answer 1

Answer:

Examples:

1. Photo decomposition is a chemical reaction in which a substance is broken down into simple substances by exposure to light (photons).
2. Decomposition 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.
3. Decomposition of potassium chlorate:When heated strongly, potassium chlorate decomposes into potassium chloride and oxygen. This reaction is used for the preparation of oxygen.
4. If the decomposition is carried out in the presence of manganese dioxide (MnO2), it takes place at a lower temperature. In this case, MnO2 is used as a catalyst.
5. Decomposition of ferric hydroxide:Ferric hydroxide undergoes decomposition in the presence of heat, giving ferric oxide and water molecules.
6. Decomposition of hydrated oxalic acid:
7. Hydrated oxalic acid (H2C2O4.2H2O) decomposes into oxalic acid and water when heated.
8. Electrolytic 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.

I hope this will be help you.
