**Experiment 11: Decomposing Baking Soda** A student collects the following data when decomposing an unknown mixture containing baking soda, NaHCO₃. Find the mass of baking soda in the sample. **Chemical Reaction:** \[2 \text{NaHCO}_3 (\text{s}) \rightarrow \text{Na}_2\text{CO}_3 (\text{s}) + \text{H}_2\text{CO}_3 (\text{g})\] **Mass Measurements:** 1. **Mass of test tube + unknown mixture (before heating):** 24.1612 g 2. **Mass of test tube + residue (after heating):** 23.8919 g **Calculations:** - **a. Mass of unknown mixture:** - **b. Mass of H₂CO₃ (before heating - after heating):** - **c. Mass of NaHCO₃ in unknown mixture and percent of NaHCO₃ in unknown mixture:** This equation aims to determine the amount of NaHCO₃ present in the unknown mixture by measuring the mass loss, attributed to the gaseous products released during decomposition.
