In the reaction, they place 50.00 g of acetic acid (CH3COOH) in a clean, dry ziploc bag and then add 5.00 g of baking soda (NaHCO3). The products of the reaction include sodium acetate, carbon dioxide, and water. In trial 1, Eli immediately seals the bag upon addition of the baking soda and waits until the bubbling comes to a halt. John weighs the closed bag with all contents and records mass in the table. For trial 2, John and Eli repeat the procedure but forgot to seal the bag. Their results are shown in the table below. 1. Calculate the theoretical mass of the open bag. 2. Are atoms/mass conserved in each of the reactions? 3. Provide mathematical evidence to explain your reasoning that atoms/mass are/are not conserved.
