Question

decomposition reaction requires energy either in the form of heat or light or electricity for Breaking Down The reactance write one equation for each for decomposition reactions where energy is supplied in the form of heat light and electricity?​

Answer 1

Answer:

(1.) Decomposition on heating

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

CaCO

3

→CaO+CO

2

(2.) Decomposition by light

Silver chloride decomposes to silver and chlorine in presence of sunlight

2AgCl→2Ag+Cl

2

(3). Decomposition by electricity

Water on electrolysis gives hydrogen and oxygen

2H

2

O→2H

2

+O

2

Answer 2

Answer:

The energy can be in light or heat or electricity energy. If the Decomposition reaction require heat energy, then it is called as thermal decomposition reaction. For example: If the Decomposition reaction require energy in the light form is known as reaction of photochemical decomposition.
