Question

decomposition reaction require energy either in the form of heat or light or electricity for breaking down the reactant . write any one equation each for decomposition reaction where energy supplied in the form of heat light and electricity

Answer 1

2FeSO4 -----> Fe2O3 +SO2+SO3

IT IS FOR HEAT

2H2O -----> 2H2 + O2

IT IS FOR ELECTRICITY

2AgCl ------> 2Ag +Cl2

IT IS FOR LIGHT

HOPE IT IS USEFUL

Answer 2

Here is the answer for your question!!!

1. CaCo3 (s) -----> Cao (s) + Co2 (g) {heat energy}

2. 2AgCl (s) -----> 2Ag (s) + Cl2 (g) {Light energy}

3. 2H2 (l) ------> 2H2 (g) + O2 (g) {Electricity}
