Question:

Let us explore a reaction with a limiting reactant. Here, zinc metal is added to a flask containing aqueous HCl, and H2 gas is a product.Zn(s) + 2 HCl(aq)  ZnCl(aq) + H(g)

The three flasks each contain 0.100 mol of HCl. Zinc is added to each flask in the following quantities.Flask 1: 7.00 g Zn Flask 2: 3.27 g Zn Flask 3: 1.31 g Zn Cengage Learning/Charles D. Winters

When the reactants are combined, the H2 inflates the balloon attached to the flask. The results are as follows: 

Flask 1: Balloon inflates completely, but some Zn remains when inflation ceases.

Flask 2: Balloon inflates completely. No Zn remains.

Flask 3: Balloon does not inflate completely. No Zn remains. Explain these results. Perform calculations that support your explanation.
