Decomposition by heat or thermal energy
caco3--->heat- cao+ co2
(b) Decomposition by light or photolysis
2AgCl —> 2Ag + Cl2 (in presence of light)
(c) Decomposition by electricity or electrolysis
2h20--->electricity ---2h2 + O2

Three chemical equations on light heat and electricity can be shown in form of decomposition reaction using light ,heat and electricity
DECOMPOSITION REACTION USISNG LIGHT:
2Agcl---->2Ag + Cl2
DECOMPOSITION REACTION USING HEAT:
CaCo3---->CaO + CO2
DECOMPOSITION REACTION USING ELECTRICITY:
2H2O---->2H2 + O2
Have a look at the picture below:
