Question

Zinc granules on treating with an acid X, form the zinc sulphate (ZnSO4) salt along with the evolution of a gas Y which burns with a pop sound when brought near to a burning candle. Identify the acid X and gas evolved Y​

Answer 1

Answer:

Zn + H2SO4 ----------> ZnSO4 + H2

(sulphuric (zinc

acid ) sulphate)

Explanation:

X - Sulphuric acid - H2SO4

Y - Hydrogen gas - H2

Answer 2

Answer:

When a metal reacts with an acid, corresponding salt is formed and hydrogen gas is evolved. The evolution of hydrogen gas is proved by the pop sound heard when It is brought near a candle The reaction is as follows -

Zn + dil H2SO4(Acid X) -> ZnSO4 + H2(Gas Y)

Zinc granule + dil. Sulfuric acid ->. Zinc sulphate + hydrogen gas

Here the acid X is H2SO4 whereas the Gas evolved is hydrogen
