Explain the three types of decomposition reaction with the help of balanced chemical equation for each.

Explanation

Thermal Decomposition
`underset("lime stone")(CaCO) overset("heat")(to) underset("Quick lime")(CaO_(s)) + underset("carbondioxide")(CO_(2(g)) uarr)`
II. Photochemical decomposition
`underset("silver chloride")(2Ag Cl_((s)) ) overset("sun light")(to) underset("silver")(2Ag_((s))) + underset(chlorine")(Cl_(2(g)) ) `
III. Electrolytic decomposition
`underset("water)(2H_2O) overset("electric current")(to) underset("hydrogen")(2H_(2(g)))+ underset("oxygen")(O_(2(g)))`
