REACTION CHEMISTRY
Our reaction involved Hydrochloric Acid and Sodium Bicarbonate.
HCl(aq) + NaHCO3(aq) H2O(l) + CO2(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 CO2
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.

CAR DESIGN
Initial Car Design: Did not move.
Base for Final Car Design
Second Car Design: Too heavy.

CONCLUSIONS
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.
