Question

X is a mixture of iron filling and sulphur and why is a product obtained by heating the mixture x and crushing it to a fine powder on burning the magnet over both x and y what will happen

Answer 1

Rahul observed X is attracted while Y is not. X is a mixture of iron and sulphur, and in a mixture the inherent properties of components are not lost. But when this mixture is heated then Iron and Sulphur react to form Iron Sulphide, which is a different compound.

A compound will not exhibit properties of the constituent elements. Iron is magnetic. But, Sulphur and Iron Sulphide are non-magnetic.

Hence only the iron from X is attracted.
