Need help question 4

**Laboratory Experiment Questions and Diagram Explanation** 1. **Part A.2**: Suppose 6 M HCl is substituted for the 3 M HCl. How does this substitution affect the sample? Will the reported percent CaCO₃ in the sample be too high, too low, or unaffected? Explain. 2. **Part A.3**: A few drops of HCl(aq) spilled over into the CaCO₃ sample prior to firmly sealing the reaction vessel. As a result of this poor technique, how will the reported percent CaCO₃ in the sample be affected? Will it be too high, too low, or unaffected? Explain. 3. **Part A.4**: The rubber stopper has a small crack resulting in a not-tight seal. How will this affect the calculated molar volume of CO₂... too high, too low, or unaffected? Explain. 4. **Part C.1**: The water level in the CO₂(g)-collection cylinder is higher than the water level outside the cylinder. Is the wet CO₂ gas pressure greater or less than atmospheric pressure? Explain. a. Is the wet CO₂ gas pressure greater or less than atmospheric pressure? Explain. b. An adjustment is made to equilibrate the water levels. Will the volume of the wet CO₂ gas increase or decrease? Explain. c. The student chemist chooses not to equilibrate the inside and outside water levels. Will the reported number of moles of CO₂ generated in the reaction be too high, too low, or unaffected by this carelessness? Explain. 5. **Part C.1**: An air bubble accidentally enters the CO₂-collection graduated cylinder after the completion of the reaction. How does this error affect the reported moles of CO₂(g) collected? Explain. **Diagram Explanation:** The diagram in the margin shows a graduated cylinder with different water levels inside and outside. This illustrates the concept of pressure differences caused by varying water levels, affecting gas measurement and volumetric calculations. Adjustments in water level equilibria are critical for accurate experimental results.
