1.

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

Answer»

SOLUTION :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)))`
