  2. Reaction Chemistry HCl(l) + NaHCO3(s)NaCl(aq) + CO2(g) + H2O(l) Solution of HCl was 12.1 M. Added 9.37g NaHCO3 with 10 mLHCl. 12.1 M * .001 mL= .0121mol HCl Molecular Weight of NaHCO3 =84g/mol, 9.37g/84g/mol=.112mol NaHCO3 HCl is in excess This reaction creates .122 mol CO2 22.4L/mol*.112mol CO2=2.5L Volume of bottle after addition of 190mL H2O and 10mL HCl=.5L 2.5L of CO2(g)/.5L=5atm

  3. Test Results

  4. Conclusion When testing the car using the Hydrochloric Acid and the Sodium Bicarbonate reaction, it was found that it resulted in many different distances, ranging anywhere from 0 feet to 50 feet each using different combinations of vehicle parts and chemical combinations. From our tests, the results were not very reliable, and the outcome was undesirable. When presented with a low distance, we altered our vehicle in order to lighten the weight, which would then give us different distance results in the next trial. But in our final trial, a chemical combination that would normally result in 20 feet gave us 50 feet. For improvements in the future trials, we should keep time measurements of how long the reaction took place before opening the bottle. It was evident that a fully reacted bottle was not as effective as a partially reacted bottle. Next time, keeping track of the distances yielded in relation to time would give us a better chance at getting closer to the 25 feet.
