I don't know. It has been years since I did that experiment.

#### Explanation:

The addition of zinc metal, as a powder, would have produced a vigorous effervescence; heat would also have been evolved. The metal powder would have gone up into solution. We can represent this reaction by the balanced chemical equation:

$Z n \left(s\right) + 2 H C l \left(a q\right) \rightarrow Z n C {l}_{2} \left(a q\right) + {H}_{2} \left(g\right) \uparrow$

We write the equation in order to establish the stoichiometry; the mass equivalence of the reactants and product.
