Answer 2

Answer:

a burning splinter

Explanation:

When HCL is react with zinc metal,zinc displaces hydrogen from the Hydrochloric acid.This reaction is a example of a displacement reaction. So in this reaction hydrogen gas is evolved. So to know whether hydrogen gas is released or not, we test it with a burning splinter.When we bring a burning splinter towards the test tube we can see burning splinter burns with a pop sound which shows that hydrogen is evolved in this reaction.
