Using the Equation below answer the following questions: a. Is there a relationship between the mass of baking soda used and the volume of the balloon? If yes, describe the relationship. b. Which one of the two reactants is left in each of the three bottles after the reaction stops? c. Which of the two reactants “limited” the amount of gas formed from the reaction? d. What do you think will happen if you used the same amount of baking soda in each bottle and then add varying amounts of vinegar? Will the result be the same as that you observed from this experiment? Why? Use this balanced equation: NaHCO3 + CH3COOH H2O + CO2 + NaC2H3O2 In an experiment, the following mass measured 3.0 grams, 5.5 grams and 7.0 grams of Baking soda is mixed with 0.5 mol of acetic acid (vinegar) to form carbon dioxide as a product formed Name of Bottle NaHCO3 (Baking Soda) Acetic Acid Calculation of Amount of Product Formed Mass Mole Volume Mole Limiting Excess A 3.0 g 0.0357 50 mL 0.5 mol NaHCO3 Acetic acid B 5.5 g 0.0655 50 mL 0.5 mol NaHCO3 Acetic acid C 7.0 g 0.0833 50 mL 0.5 mol NaHCO3 Acetic acid
