Solution

Reaction:
Zn + 2HCl ZnCl2 + H2

The gas evolved is hydrogen.
If we bring a matchstick close to the mouth of the test tube evolving hydrogen gas then there is instant spark of fire because hydrogen gas catches fire and produces a pop sound. This is due to hydrogen reacts with oxygen present in air to form water vapours.
