Hydrogen Sulphide

Statement-1: In neutral solution, there is partial precipitation of zinc sulphide by hydrogen sulphide gas. Statement-2: The complete precipitation of zinc sulphide takes place by hydrogen sulphide gas when alkali metal acetate is added to the solution.

A mineral containing iron(II) sulphide but no other sulphides is treated with excess hydrochloride acid to produce hydrogen sulphide. . If a 3.15g sample of the mineral yields 448 mL of hydrogen sulphide gas (measured at 0^(@)C and 760 mm Hg), what is the mass percentage of iron (II) sulphide inthe sample?

An aquous solution of a substance give a white precipitate on tretement with dilute hydrochloric acid, which dissolve on heating. When hydrogen sulphide is passed through the hot acidic solution, a black precipitate is observed.the substance is a

Bacteria that live around deep sea, hot water vents obtain energy by oxidising inorganic hydrogen sulphide. They use this energy to build organic molecules from carbon obtained from the carbon dioxide in the seawater. These bacteria are
