Question

explain the difference in the behavior Shown by Fe+S mixture and FeS compound when the magnet is brought near them

Answer 1

Fe is attracted by magnet
S can dissolve in carbon disulphide
butttt
FeS is niether attracted by magnet nor it dissolves in carbon disulphide
HOPE THIS HELPS U

Answer 2

Answer:--One is a mixture of two unreactedelements, the other is a single substance that is a compound of both iron and sulfur.

Explanation:Iron (Fe) is a metal and is in the zero oxidation state. Equally sulfur (S), being elemental will be in its zero oxidation state. It is most commonly a yellow powdery solid. With them unreacted you will just get a mixture of both. Like mixing sand with salt say.If you REACT iron with sulfur (they will slowlyreact anyway but much better if you heat them together) then they will exchange electrons. Sulfur will gain two to go into the 2- oxidation state.Iron is more complicated as it is a transition metal and can have either a stable 2+ or 3+ oxidation state. The electrons it loses to get to this go to the sulfur atoms.If it's in the 2+ oxidation state you will get FeS as the neutral compound.If it's in the 3+ oxidation state you will get Fe_2S_3

Either of these will have chemical properties completely different to the two original elements, the same as water (H_2O) is a liquid whereas hydrogen and oxygen are both gases.
