Is there evidence that the amount of product formed is related to the amount of reactants used? Is there evidence that some of the baking soda has not completely reacted in one or more of the bags? Open each bag and add 15mL of vinegar to each. Is there evidence that a shortage of vinegar was limiting the production of carbon dioxide gas in some bags? Add 15mL of baking soda to each bag. Is there evidence that a lack of baking soda was limiting the production of carbon dioxide in some bags?
