A metal `X` is found in the form of filings which burns vigorously when sprinkle on flame. When these filings are treated with sulphur a black colured compound `Y` is formed which is not attracted by magnet. `X` reacts with dil HCl to liberate hydrogen gas. `X` reacts with steam to form `Z` along with hydrogen gas. Identify `X`, `Y`, and `Z`. Write the reaction involved.
