Answer 2

Hydrogen sulphide is a compound. (option D)

- A chemical compound is a substance which is made out of two or more chemical elements which are chemically bonded with each other.

- Only the hydrogen sulphide is the substance in the above mentioned question which qualifies all the criteria of being a chemical compound.

- On the other hand, stainless steel is iron which is physically mixed with some other metals. Graphite is just carbon and bronze is physical mixture of copper and tin.

All of these substances does not qualify for the requirements of being a chemical compound.
