Question

Decomposition reaction require energy in the form of heat,light or electricity for breaking down the reactant.write one equation for decompstion reaction where energy is suppiled in the form of heat,lighy or electricity

Answer 1

Answer:

Decomposition on heating 

Calcium carbonate when heated gives quicklime (CaO) and carbon dioxide 

CaCO3→CaO+CO2 

(2.) Decomposition by light 

Silver chloride decomposes to silver and chlorine in presence of sunlight 

2AgCl→2Ag+Cl2 

(3). Decomposition by electricity 

Water on electrolysis gives hydrogen and oxygen 

2H2O→2H2+O2
