Answer:

the reaction of sulphuric acid and Magnesium metal is as follows:

Mg + H2SO4 → MgSO4 + H2

-Hydrogen gas is evolved from the test tube in this reaction.

- When we bring the candle near the mouth of the test tube, this hydrogen gas burns explosively in the presence of air with a pop sound.
