Question

Need help with question 1

**Laboratory Questions** Circle the questions that have been assigned. 1. **Part A.1.** The water for the pan (Part A.3) is not saturated with CO₂. Will the reported percent CaCO₃ in the original sample be too high, too low, or unaffected? Explain. 2. **Part A.2.** Suppose 6 M HCl is substituted for the 3 M HCl in the procedure. What would be the consequence of this substitution? Explain. 3. **Part A.3.** A few drops of HCl(aq) spilled over into the CaCO₃ sample prior to firmly seating the stopper and prior to collecting any CO₂(g). As a result of this poor technique, will the reported percent CaCO₃ in the sample be too high, too low, or unaffected? Explain. How will this affect the calculated mole?
