I think its hydrogen.

It's. Hydrogen
No it depends on acid if it is HCl and H2SO4 then the gas evolved is hydrogen gas but if acid is HNO3 then the gas evolved is NO2
Yeah..but most of the common acids are hcl and h2so4

When a metal reacts with a dilute acid like HCL , HNO3 etc . Hydrogen gas is evolved .
The reaction can be shown as follows :
2M + dil. 2HCL → 2MCL + H2↑
Hydrogen gas can be identified by bringing a burning matchstick near the mouth of the test tube in which reaction takes place . Hydrogen gas will burn with a pop sound .
