1.	Decomposition reactions require energy either in the form of heat or light or electricity for breaking down the reactants. Write one equation each for decomposition reactions where energy is supplied in the form heat, light and electricity.
Answer» Solution :Decomposition of FERROUS sulphate `underset("Ferrous sulphate")(2FeSO_(4))(s)overset("Heat")(to)underset("Ferric oxide")(Fe_(2)O_(3))(s)+SO_(2)(g)+SO_(3)(g)` Energy supplied in the form of light : Decomposition of silver CHLORIDE `2AgCl(s)overset("Sunlight")(to)2AG(s)+Cl_(2)(g)` Energy supplied in the form of electricity : ELECTROLYSIS of water `2H_(2)O overset("Electricity")(to)2H_(2)(g)+O_(2)(g)`
