1.	The oxidation number of sulphur in S_(8),S_(2)F_(2),andH_(2)S respectively, are ____
Answer» 0, +1 and -2 `+2,+1and-2` `0,+1and+2` `-2,+1and-2` Solution :`S_(8)` is elemental form `THEREFORE` S = 0 `S_(2)F_(2)rArr2(S)+2(E)=0` `therefore2(S)+2(-1)=0` `therefore2S=2" "thereforeS=1` `H_(2)SrArr2H+S=0` `therefore2(+1)+S=0" "therefore S=-2`
