Question

decomposition reaction and equation lecture in the form of heat or light electricity for Deccan down the reaction write one equation for decomposition reaction where energy supplied in the form of heat light electricity

Answer 1

Heat - FeSO4= (heat) Fe2O3 +SO2+SO3

Electric city -H2O=(electric current) 2H2+ O2

Light - 2AgCl =(sunlight) 2Ag+ Cl2

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}
