Question

Write three example of decomposition reaction
in which heat energy, light energy and electric
energy is used. Also balance these chemical
equation.
​

Answer 1

hi mate hope it helps you

heat energy ( thermal decomposition reaction )

CaCO3=CaO+CO2⬆️

2MgO=2Mg+O2⬆️

light energy (photolytic decomposition reaction)

2AgCl=2Ag+Cl2

2AgBr=2Ag+Br2

electric energy (Electrolytic decomposition reaction)

2H2O=2H2+O2

NaCl=Na+Cl2
