`10g` of a sample of silver which is contaminated with silver sulphide produced `11.2mL` of hydrogen sulphide at S.T.P. by treatment with excess of hydrochloric acid.The amont of silver sulphide in the sample is - `(Ag=108;S=32)`

Which of the following on reaction with H_(2)S does not produce metallic sulphide ?

An impure sample of sodium chloride that weighed 0.50 g gave 0.90 g of silver choride as precipitate on treatment with excess of silver nitrate solution. Calculate the percentage purity of the sample.

An impure sample of sodium chloride which weighed 1.2 gram gave on treatment with excess of silver nitrate solution 2.4 gram of silver chloride as the precipitate. Calculate the percentage purity of the sample.

Which one of the following does not produce metallic sulphide with H_(2)S ?

If 10 g of Ag reacts with 1 g of sulphur, the amount of Ag_(2) S formed will be [Atomic weight of Ag=108, S=32]?

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?

IN the analysis of 0.5 g sample of feldspar, a mixture of chlorides of sodium and potassium is obtained which weighs 0.1180 g . Subsequent treatment of the mixed chlorides with silver nitrate gives 0.2451 g of silver chloride. What is the percentage of sodium oxide and potassium oxide in the sample ?

Calculate the mass in grams of 0.17 mole of hydrogen sulphide , H_(2)S . (Atomic masses : H = 1 u, S = 32 u )
