1.

Write one equation each for decomposition reactions where energy is supplied in the form of heat, light or electricity.

Answer»

SOLUTION :(a) Decomposition by the use of heat :
`{:("(i) "2Pb(NO_(3))_(2)(s)overset("Heat")(to)2PbO(s)+4NO_(2)(G)+O_(2)(g)),("(ii)"CaCO_(3)(s)overset("Heat")(to)CaO(s)+CO_(2)(g)):}`
(B) Decomposition by the use of LIGHT :
`{:("(i) "2AgCl(s)overset("Light")(to)2Ag(s)+Cl_(2)(g)),("(ii) "2AgBr(s)overset("Light")(to)2Ag(s)+Br_(2)(g)):}`
(c) Decomposition by the use of electricity :
`2H_(2)O(L)overset("Electricity")(to)2H_(2)(g)+O_(2)(g)`
