Hey mate!
When zinc reacts with steam Hydrgen gas is released.
Zn+ H20 ----> ZnO + H2
A lighted match stick is brought near the mouth of a test tube containing H2 gas. What will be the result?
A ‘squeaky pop’ sound will be heard, as you ignite the H2H2 gas.
The procedure you have described is often used to test for the presence of hydrogen gas. It is informally named ‘the squeaky pop test’. You bring a lit splint to the mouth of a test tube containing suspect gas (the gas which you are testing). The positive result is that you hear the squeaky pop, and thus you have evidence that the suspect gas does indeed contain H2H2. (A small amount of) water is produced by the combustion reaction which takes place, but you are unlikely to be able to observe this. The equation of the reaction is:
2H2+O2→2H2O2H2+O2→2H2O
(hydrogen + oxygen → water)
Hope it helps(^^)

The reaction will be
Zn + H20 ------- ZnO + H2.
When a burning machstixk brings to it , it will produce pop sound because of hydrogen gas will released.
Hope it will help you.
