Zn(s)+2 HCl(aq)-->ZnCl2(aq)+H2(g)
The three flasks each contain 0.350 mol of HCl. Zinc is added to each flask in the following quantities: 5.72g, 11.4g, 22.9 g. 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.
What mass of Zn was added to each flask?
Mass (flask 1)=_____g
Mass(flask 2)=______g
Mass(flask 3)=______g
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
