Do the observed relative sizes of the inflated balloons agree with the calculated theoretical yield for CO2?
Homework Answers
1mole of gas occupied volume =22.4 L at STP.
Theoretical amount (in moles) of CO2 in balloons
Balloon1<< balloon2 <balloon3
Volume of gas in balloons
Balloon1<< balloon2 <balloon3
Relative size of balloons--
Balloon1<<balloon2 <balloon3
Thus observed relative sizes of balloons agreed with theoretical yeilds.

I need help answering these questions.
1. As the reaction was theoretically performed in a
closed system, there should be no change in mass before and after
the reaction. What are possible sources of error in your experiment
reactions?
2. The chemical reaction you investigated is a two-step
reaction. What type of reaction occurs in each step? How did you
determine your answer?
