Question
100%
The zinc within a copper-plated penny will dissolve in hydrochloric
acid if the copper coating is filed down in several spots (so that
the hydrochloric acid can get to the zinc). The reaction between
the acid and the zinc is as follows:
Part A
2H (aq)Zn(s) -> H2(g) Zn2(aq)
What mass of hydrogen gas was collected?
When the zinc in a certain penny dissolves, the total volume of
gas collected over water at 25 °C was 0.957 L at a total
pressure of 758 mm Hg .
