Answer: C
Explanation:
From the question, "... Gas Y which burns with a pop sound when brought near to a burning candle". The test for hydrogen gas is to hold a burning splint near the top of the test tube and listen for a "pop" sound, which indicates the presence of hydrogen. Since there is a "pop" sound, gas Y is hydrogen.
Meanwhile, the zinc granules are treated with an acid X that give rise to the product zinc sulphate. Because sulphate is produced from the reaction, X contains sulphate ions and is thus sulphuric acid and not hydrochloride acid, in order to form zinc sulphate.
H2SO4 + Zn = ZnSO4 + H2
(Note that the hydrogen gas came from this reaction)
