Question

write a equation for electrical decomposition and thermal decomposition

Answer 1

Thermal decomposition reaction (Thermolysis)

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.
CaCO3(solid)+ Heat ---------------> CaO(s)+CO2(g)


......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.
2H2O(liq) + electric current -------> 2H2 (g)+O2(g)
