REACTION POWERED CAR
“THE BOSS”
By: Blake Inglin, Rachel Dana, and Priya Gupta
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.
GO BEAVERS!!
