11. PV Work: "Wack-A-Pack" balloons inflate when you whack them. Inside each balloon are citric acid (H,CH5O7), sodium bicarbonate (NaHCO3), and water. The balloon has a volume of 266 mL when fully inflated. The temperature is 22.0C and the atmospheric pressure is 754 mm Hg. If there are 2.00 g of citric acid and 2.50 g sodium bicarbonate are inside the balloon with 5 mL of water: H-CHO-(aq) + 3 NaHCO3(aq) Na3C6H5O- (aq) + 3 CO(g) + 3 HO(1) A. What is the pressure inside the balloon after the reaction is over? B. How much PV work (in J) is done as the balloon inflates? State any assumptions that are necessary to complete the calculation. the 00 MIELATED YOUR Fagers BALL POOFI 3 SET VES
