Write balanced chemical equation for the following reactions:
(i) Permanganate ion reacts with sulphur dioxide gas in acidic medium to produce
and hydrogensulphate ion.
(Balance by ion electron method)
(ii) Reaction of liquid hydrazine with chlorate ion
in basic medium produces nitric oxide gas and chloride ion in gaseous state.
(Balance by oxidation number method)
(iii) Dichlorine heptaoxide in gaseous state combines with an aqueous solution of hydrogen peroxide in acidic medium to give chlorite ion
and oxygen gas.
(Balance by ion electron method)
