Write a balanced equation for the process taking place during the pop test?

Write a balanced equation for the reaction of zinc metal and hydrochloric acid to form hydrogen gas.

Zn+ 2HCl→ ZnCl2+ H2

So I did that^^

And now its asking for the equation of the process taking place during the "pop test"

So how do you write that?

fire + hydrogen = pop??

Because the next question requires the use of this pop test formula to work out some enthalpies.

Thanks for any help at all :))

    You write the same equation and say that due to evolution of H2 in above reaction we get a pop sound on keeping a burning splinter at the mouth of the test tube.
