A student heats calculated amounts of iron filings and sulphur powder together in a boiling tube. He will obtain (3) a homogeneous compound of FeS
The correct answer is option 3
Explanation:
When iron and sulphur are heated in the boiling tube, they react to form a gray-black iron sulphide compound. The resulting compound is homogeneous, that is to say, that the two elements are completely mixed and cannot be divided.
The chemical equation is as follows
Fe + S ---> FeS
Therefore the correct answer is option 3
