2.  1NaHCO 3 + 1HCl → 1CO 2 + 1NaCl + 1H 2 O Baking Soda Hydrochloric Acid Carbon Dioxide Salt Water N=PV/RT P=5atm V=.7L R=.08205Latm/molK T=293K N=(5atm x.7L)/(.08205Latm/molK x 293K) N=.1456moles HCl calculation:.1456mol/12.1molHCL x 1000mLHCl= 12.0320mLHCl to be used to keep reaction at 5atm. Baking Soda calculation:.1456mol x 84.008gB.S. = 12.2305g B.S. to be used in reaction to keep reaction at 5atm pressure.

3. Car design consisted of simplicity to minimize the weight and of strength to make sure the car did not fall apart when it moved.

4. We used the same amount of HCl and Baking Soda every time because we did not want to exceed 5atm pressure on the bottle.

5.  Our car performed reasonably well going within 3 feet of the 25ft finish line.  However due to the bottles weakening and leaking caps our results were not very consistent and were very spread out.  If we were to redesign this vehicle we would find a plastic bottle that could withstand more pressure so it wouldn’t warp causing our results to be more consistent.
