Two students design an experiment to prove that mass is conserved during a chemical reaction. They attach a balloon to a flask containing 100.00 g of water and 1 antacid tablet. The antacid tablet is
dropped into the water where it begins to react, producing carbon dioxide gas. The antacid tablet weighs 3.24 9. The total mass before reaction is 103 24 g Antacid is a mixture of citric acid, sodium
bicarbonate, and aspirin and reacts with water producing a sodium citrate solution, carbon dioxide, and aspirin
