Mary wants to model a volcanic eruption for her 5th grade science fair project. She combines baking soda
(NaHCO3) and vinegar (HC₂H₂O₂) to create the eruption. The eruption bubbles up and spills over the side of her
volcano. Mary formed sodium acetate (NaC₂H₂O₂), water (H₂O) and carbon dioxide (CO₂) in the simulated
eruption.
