Question

What happens when zinc reacts with dilute hydrochloric acid ?

Answer 1

Answer:

Zn + HCl = H2 + ZnCl2

It is a single displacement reaction where -

Zinc is oxidised (it becomes positive) and water is neutralized. It is a reduction-oxidation reaction where one of the reactants loses oxygen and the other one gains.

So, answering your question, we get hydrogen gas and a salt.

Hydrogen gas, is identified by exposing it to a burning flame. It explodes (a bit,) with a pop sound. This is because Hydrogen is highly explosive.
