Question

Give one example each of thermal decomposition, photo decomposition& electrolytic decomposition .

Answer 1

Examples are:
Thermal decomposition -calcium carbonate (CaCO3 ) in presence of heat decomposes to give calcium oxide(CaO) and carbon dioxide (CO2)
Photo decomposition -twice silver chloride(2AgCl) in presence of sunlight decomposes to give two silver(2Ag) and chloride (Cl2)
Electrolytic decomposition - water(H2O) in presence of electricity decomposes to give hydrogen (H2) and oxygen (O2).

Answer 2

Thermo decomposition =when limewater is shaken CO2 is decom

posed

Photo decomposition = decomposition of potassium chlorate.

Electrolytic = electroplating of silver on spoon
