1. Given that a theoretical yield for isolating Calcium Carbonate in this experiment would be 100%. From that information and based on the results you obtained in this experiment, describe your success in the recovery of calcium carbonate and suggest two possible sources of error that would have caused you to not obtain 100% yield. from my result my percent yield was 102%

Question

1. Given that a theoretical yield for isolating Calcium Carbonate in this experiment would be 100%. From that information and based on the results you obtained in this experiment, describe your success in the recovery of calcium carbonate and suggest two possible sources of error that would have caused you to not obtain 100% yield.

from my result my percent yield was 102%

### Experiment Data: Calcium Carbonate (CaCO₃) Precipitation #### Initial Data: - **CaCl₂•2H₂O (g):** 1.50 g - **CaCl₂•2H₂O (mol):** 0.0102 mol - **CaCl₂ (mol):** 0.0102 mol - **Na₂CO₃ (mol):** 0.0102 mol - **Na₂CO₃ (g):** 1.08 g #### Theoretical Yield: - **Theoretical CaCO₃ (g):** 1.02 g #### Measurements: - **Mass of Filter Paper (g):** 0.86 g - **Mass of Filter Paper + CaCO₃ (g):** 1.90 g #### Results: - **Actual CaCO₃ (g):** 1.02 g - **Percent Yield:** 102% #### Notes: This table presents the data for a typical chemical reaction involving the precipitation of calcium carbonate (CaCO₃) from a reaction between calcium chloride (CaCl₂) and sodium carbonate (Na₂CO₃). The mass of CaCO₃ obtained is slightly higher than the theoretical prediction, resulting in a percent yield of 102%. Possible reasons for a percent yield over 100% could include measurement errors or impurities.
