That depends on what chemicals were mixed in order to produce the hydrogen gas. For example, if it was the metal magnesium (Mg), and the acid hydrochloric acid (HCl), then the equation would be Mg(s) + 2HCl(aq) -- > MgCl2(aq) + H2(g). Please note that the 2 after MgCl is supposed to be a subscript, as is the 2 after hydrogen. We are having difficulties with the subscripts and superscripts right now.
The pop test equation is: 2H2 + O2 --> 2H2O
Hydrochloric acid+ magnesium = magnesium chloride + hydrogen
The reaction is:
Mg + 2 HCl = MgCl2 + H2

the hydrogen pop test
The "squeaky pop" test. You burn a wooden splint and put it in the contained hydrogen gas. If hydrogen is present you will hear a pop.
Do the "Pop test"-A lit taper placed in hydrogen gas will make an audible pop.
It is called the 'pop test' in which you light a wooden spill and put in then test tube if hydrogen is present you hear popping noises.
To confirm the presence of hydrogen gas, you take a lit splint and insert it into the test tube or the container with the gas, and there should be a loud 'pop' as the hydrogen gas ignites. This is the easiest and most effective test. http://www.gcsescience.com/itesthydrogen.htm

In the lab. and for small quantities. use the 'pop' test. Allow the hydrogen to be in contact with oxygen, then put a flame to it. It will 'pop'.

Squeaky Pop Test -Place a lit wooded splint into the hydrogen a squeaky pop will be heard if hydrogen is present. To be used for small amounts of hydrogen
well, to check you have to preform the pop test. the pop test is a test that you add fire to the container that the acid is in. if it pops its hydrogen but if it doesn't its carbon dioxide.
in other words the squeeky pop test
place a lit splint into a test tube if you hear a squeaky pop sound it is hydrogen.
