When 5 ml of dilute HCL is added to a mixture of iron fillings and sulphur powder which gas is evolved?

When dilute hydrochloric acid (HCl) is added to a mixture of iron filings and sulfur powder, hydrogen gas (H₂) is evolved. The acid reacts with the iron filings, leading to the formation of iron chloride and the release of hydrogen gas. Sulfur does not react with hydrochloric acid under these conditions, so it does not contribute to the gas evolved.
