The Great Balloon Race Background: We will be reacting various amounts of sodium bicarbonate with a constant amount of acetic acid (see table 1) resulting in the following reaction: NaHCO 3 (s) + CH 3 COOH (aq) b NaCH 3 CO 2 (aq) + CO 2 (g) + H 2 O (l) The resulting CO 2 (g) produced will cause the balloons to inflate. Table 1: Flask Number: Amount of NaHCO 3 (s) Amount of CH 3 CO 2 H (aq) 1 0.50 g 0.030 moles 2 1.50 g 0.030 moles 3 3.00 g 0.030 moles Pre Race Questions: 1. Which balloon do you believe will inflate the fastest? Why? 2. Which balloon do you believe will inflate the most? Why?

NaHCO 3 (s) + CH 3 COOH (aq) b NaCH 3 CO 2 (aq) + CO 2 (g) + H 2 O (l) Post Race Questions: 3. Which balloon inflated the fastest? Why? 4. Which balloon inflated the most? Why? 5. Which reactant was the limiting reactant in each trial? 6. Which reactant was in excess in each trial? 7. What was the theoretical yield, in moles, of CO 2 for the reaction that utilized 3.00 g of sodium bicarbonate? 8. One mole of gas at STP (standard temperature and pressure) has a
