Theoretical Predictions CONTINUATION

Ideal gas law- arrange to solve for n

Since the reaction is 1:1 mole ratio we can predict that HCl and Baking soda is 0.145 moles

•Generally the car performed well because of its unique design and intense group care.

• The car didn’t spew in the most of runs especially in the final tests.

•We maintained good table of data so we can know if any errors happens.

•The citric acid experiment failed but the car moved to 10 ft maximum after couple of runs.

Dear Dr. Skip,

During this term fall 2009, we have enjoyed our times in your class. You are totally a great instructor. We have gained allot of knowledge through the whole term and the stuff covered in the class were interesting and important. You were emphasizing on materials that will help us in engineering major later on. There are many qualities that you own. You were a great helper to the students especially us. Finally, we wish you the best of the best and have great winter break with your family!

Regards,

Ammar AlsaeedGina PimentelTyler Folkman
