Question

write one equation each for decomposition reaction where energy is supplied in the form of heat light or electricity​

Answer 1

thermal decomposition (heat)

2FeSO4 on heating gives Fe2O3 + SO2 + SO3

LIGHT

AgClin presence of light gives 2Ag + Cl2

electricity

2H2O gives 2H2+ O2

Answer 2

HEYA

Here is your answer :--->

Decomposition Reaction is the chemical reaction in which one chemical compound decomposes to form two or more simpler substances.

• Decomposition by heat :-
• When a chemical compound breaks down into its simpler substances by supplying heat to it

Example --- >

heat ∆

CaCO3 -----------> CaO + CO2

2. Decomposition by light ---

When chemical compound broke into its simpler substances by action of sunlight on it.

Example ---->

sunlight

2AgCl ---------------> 2Ag + Cl2

3. Decomposition by electricity ----

When a chemical compound breaks into the simpler substances by conduction of electricity through it.

Example -

electric current

2H2O ----------------> 2H2 + O2
