Identify the oxidised and reduced species in the following reactions: (a) `CH_(4(g))+4Cl_(2(g))rarrC Cl_(4(g))+4HCl_((g))` (b) `MnO_(2(s))+C_(2)H_(2)O_(4(aq.))overset(2H^(+))rarrMn_((aq.))^(2+)+2CO_(2(g))+2H_(2)O_((l))` (c ) `I_(2(aq.))+2S_(2)O_(3(aq.))^(2-)rarr2I_((aq.))^(-)+S_(4)O_(6)^(2-)` (d) `Cl_(2(g))+2Br_((aq.))^(-)rarr2Cl_((aq.))^(-)+Br_(2(aq.))`

Answer» `{:(,"Reduced",,"Oxidised",),((a),Cl_(2),,CH_(4),),((b),MnO_(2),,C_(2)H_(2)O_(4(aq.)),),((c ),I_(2),,S_(2)O_(3)^(2-),),((d),Cl_(2),,Br^(-),):}`
