THURSDAY Mr. Pate's science class performed an experiment involving the chemical reaction of sodium bicarbonate (baking soda) and vinegar . Students poured 50 mL vinegar into a small bottle, then added sodium bicarbonate to a balloon. They attached the balloon to the bottle and dumped the sodium bicarbonate into the bottle. The resulting reaction produced carbon dioxide gas, which filled the balloon. Lanie hypothesized that the more sodium bicarbonate that was added to the vinegar, the bigger the balloon would get. Victor hypothesized that more than 8 g of sodium bicarbonate would cause the balloon to pop. . The Effects of Sodium Bicarbonate Levels on Gas Production in 1. Was Lanie's hypothesis correct? a Chemical Reaction Explain your answer. Trial 1 Trial 2 Trial 3 Trial 4 2. Was Victor's hypothesis correct? Explain your answer, Mass of Sodium Bicarbonate 59 7.5 9 3. What could the students expect Added the balloon circumference to be if Balloon 12.5 g of sodium bicarbonate were 30 cm 38 cm 44cm 51 cm Circumference added? 2.5 g 10 9
