Give one example each of :
(i) Thermal decomposition reaction
(ii) Electrolytic decomposition reaction
(iii) Photo decomposition reaction.

Explanation

(i) `CaCO_(3)(s) overset("Heat")to CaO(s) + CO_(2)(g)`
(ii) `2H_(2)O(l) overset("Electric")to 2H_(2)(g) + O_(2)(g)`
(iii) `2H_(2)O_(2)(l) overset("Light")to 2H_(2)O(l) + O_(2)(g).`
