With mercury
Sulphur is very reactive with mercury and can combine even at the temperature of liquid air (-200oC). Usually both are rubbed together to make them combine.
With sodium
The reaction of sulphur with sodium is as follows:
With Iron
Iron and sulphur combine on heating to form iron (II) sulphide, evolving a large quantity of heat energy.
With Copper
On heating to about 400oC, copper combines with sulphur to form cuprous sulphide.
If the temperature is above 400oC, then cupric sulphide is formed.
Introduce a thin copper sheet into boiling sulphur. Copper ignites spontaneously to form cupric sulphide (Fig.13.31).
With zinc
The reaction of sulphur with zinc is as follows:
