Question

Decomposition reactions require energy eithere in
the form of heat or light of electricity for
breaking down the reactants. write one equation
each for decomposition reactions where energy
is supplied in the form of heat. Light and
electricity.​

Answer 1

Answer:

Decomposition reaction requires energy either in the form of heat and light or electricity for breaking down the reactants. write one equation for decompostion reaction where energy is supplied in the form of heat .light and electricity

i) Decomposition due to heat: Thermal decomposition

CaCO_3(s)\rightarrow CaO(s)+CO_2(g)

ii) Decomposition due to light: Photolytic decomposition

2AgBr(s)\rightarrow 2Ag(s)+Br_2(g)

iii) Decomposition due to electricity: electrolytic decomposition

2H_2O(l)\rightarrow 2H_2(g)+O_2(g)
