(c) X-Hydrochloric acid and Y-Oxygen gas
(d) X-Hydrochloric acid and Y-Rydrogen gas​

Answer 1

Answer:

B) X - Sulphuric acid and Y - Hydrogen gas

Explanation:

When acid reacts with metal it forms salt and hydrogen gas.

Zn + H2SO4   → ZnSO4 + H2

Also the chemical formula you have given for zinc sulphate is wrong. The

correct formula is ZnSO4.

Hope it helps!
