Answer:
If the metal is not very reactive such as copper, no gas would be evolved. But if a reactive metal is treated with sulphuric acid, the gas that will be evolved is Hydrogen. We can hear a pop sound of hydrogen burning, which can be used to test the gas.
If zinc is treated, the hydrogen will be evolved.
Hydogen is used as a propellant in rockets.
