Part D: Pipette Bulb "Rockets" 1. Report how far the pipet bulb travelled with various ratios of hydrogen to oxygen gas in Table 7.3. Distance Table 7.3: Distance traveled for different H₂:0₂ ratios 100% H₂H₂:0₂H₂:0₂H₂:0₂H₂:0₂ MAX distine 2. O Summer 2022 C O Report: Experiment 7 Which ratio of hydrogen to oxygen travelled the greatest distance? (a) Calculate the moles of hydrogen in this sample. (b) Calculate the moles of oxygen in this sample. MX distance 50% (c) What is the ratio of hydrogen to oxygen in this sample? H₂:0₂ 100% O₂ 0 H₂O (1) CHEM 1215 3. Balance the chemical reaction for the combustion of hydrogen and oxygen gas in Eqn. 7.5. H₂(g) + O₂(g) → (7.5) 4. How does your optimized ratio of hydrogen to oxygen (See Question 2c) compare to the coefficients in the balanced chemical reaction? In 2-3 sentences, briefly explain whether this fits your expectations or not. 83
