too low, or unaffected? Explain.
3. Part A.3. A few drops of HCI(ag) spilled over into the CaCO3 sample prior to m
y Part A.4. The rubber stopper has a small crack resulting in a not-tight seal. How will this affect the calculated
volume of CO,... too high, too low or unaffected? Explain.
3. Part C.1. The water level in the CO,(g)-collection cylinder is higher than the water level outside the cvlin 1
See margin drawing.
a. Is the wet CO2 gas pressure greater or less than atmospheric pressure? Explain.
Explain.
C. The student chemist chooses not to equilibrate the inside and outside water levels. Will
the reported number of moles of CO, generated in the reaction be too high, too low, or
unaffected by this carelessness? Explain.
6. Part C.1. An air bubble accidentally enters the CO,-collection graduated cylinder after the
comnletion of the reaction. How does this error affect the reported moles of CO2(g)
