Question

decomposition reactions require into energy either in the form of heat or light or electricity for breaking down reactance write one equation for each decomposition reaction where energy is supplied in the form of heat light and electricity

Answer 1

Thermal decomposition reaction: brought about by heat.

Caco3 (s)______》cao (s)+co2.

Photolysis: brought about by light.

2Agcl (s)_____》2Ag (s)+click.

Electrolysis: brought about by electricity .

2Nacl(l)______》2Na (s)+Cl2

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}
