2. The Group

3. Calcium Carbonate and Hydrochloric Acid
The Chemistry
Calcium Carbonate and Hydrochloric Acid
CaCO3 + 2HCl → CO2 + H2O + CaCl2
Theoretical Calculations:
n = PV / RT
P=5.0atm V=.675L R= atm*L/K*mol T=293K
n = mol
Reactants
14.053g CaCO3 used
25.0 mL HCl used

4. And The Car
The design of the car was very simple, make it small and lightweight. The back wheels were wider than the front for more stability. The bottle was pointed up to prevent any spew, and at the base of the bottle was a solid bar so all the force would be put into moving the car, not the bottle.
Ready For Takeoff!!!

6. Conclusion Redesign Ideas Car made it to the finals with no spew!
One trial made it to 25' 2'' and the rest were consistently short stopping around 21'.
During one trial the car bottle blew up. The simple design of the car was good because it could be rebuilt in a few minutes to continue running more trials. However, the car did not go straight, possibly because the frame did not stay square.
Redesign Ideas
Another cross support could be added to the car to help keep the frame square. This will help the car to go straight, making the car stop close to 25'. Also for the aesthetics we could have decorated our car but we didn't want it to hinder our scientific studies.
