Question

activity of zinc reacts with hydrochloric acid

Answer 1

Answer:

Explanation:

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.

Answer 2

Explanation:

The reaction between zinc and hydrochloric acid is Zn + HCl = H2 + ZnCl2. It is a single replacement reaction where zinc metal displaces the hydrogen to form hydrogen gas and zinc chloride, a salt. Zinc reacts quickly with the acid to form bubbles of hydrogen.
