2. R EACTION C HEMISTRY Our reaction involved Hydrochloric Acid and Sodium Bicarbonate. HCl (aq) + NaHCO 3(aq) H 2 O (l) + CO 2(g) +NaCl (aq) Calculations were done to find how many milliliters of HCl we could use without going over 5 atm. 12 mL x 12.1 moles HCl =.1452 mol HCl =.1452 mol CO 2 1000 mL HCl PV=nRT P=nRT/ V (.1452 mol)(.0821 Latm/molK)(293K)/(.700 L) P = 4.9898 atm This was our theoretical prediction of the pressure in the bottle using 12 mL of HCl.

5. C ONCLUSIONS Our car went to finals with a distance of 29 inches away from the goal of 25 feet. In finals we finished with a distance of 2 inches away from 25 feet. If we were to redesign our car, we would make our car more stable by creating a stronger support for the bottle and use bigger wheels. We would also make a more durable to withstand pressure and crashes. Our car was extremely inconsistent during the competition and we expect that making these changes would increase consistency.
