In the reaction given below identify the species undergoing oxidation

1.	In the reaction given below identify the species undergoing oxidation and reactioin : (i) CH_(4)(g)+2O_(2)(g)rarr CO_(2)(g)+2H_(2)O(i) (ii)H_(2)S(g)+O_(2)(g)rarr2s(s)+2H_(2)O(l) (iii)CH_(2)=CH_(2)(g)+H_(2)(g)rarrH_(3)C-CH_(3)(g) (iv)HgO(s)rarr2Hgl)+O_(2)(g) (v)Mg(s)+S(s)rarr MgS(s)
Answer» Solution :(i) `CH_(4)` is oxidised to `cO_(2)` while `O_(2)` is reduced to `H_(2)O` (ii) `H_(2)S` us ixudused TI S wile `O_(2)` is reduced to `H_(2)O` (III) `CH_(2)=cH_(2)` is rduced to`CH_(3) rarr CH_(3)` while `H_(2)` is oxidised to `CH_(3)-CH_(3)` (iv) `HG^(2+)` is reduced to Hg whle `O^(2-)` is oxidised to `O_(2)` (v)Mgis oxiised to `Mg^(2+)` while S is reduced to `S^(2-)`
