Question

When a zinc metal is placed in dilute HCl

Answer 1

Answer:

Zn + HCl = H2 + ZnCl2

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.

Answer 2
