Problem Details

A diagram shows a flask containing HCl (aqueous).  The top of the flask leads to a piston, and the side of the flask has a small inlet for Zn (solid).  After some zinc is added, the inlet is closed, and the following reaction takes place in the flask: Zn (solid) plus 2 H+ (aqueous) goes to Zn2+ (aqueous) plus H2 (gas). The flask now contains H2 gas plus the original atmosphere.  The piston has moved up; the increase in volume means the system does pressure-volume work.
