Ms. M's students are currently engaged in crafting experiments centered around the utilization of baking soda and vinegar. Within Group 1, they commence by introducing 25 grams of vinegar into a flask and depositing 5 grams of baking soda into a balloon, securing the balloon over the flask's opening, and subsequently merging the baking soda and vinegar. The flask's weight is monitored continuously throughout the experiment, and the accompanying image depicts the experimental setup conducted by Group 1.

Question

Group 2 follows a comparable procedure but opts not to employ a balloon. Instead, they transfer an equivalent quantity of baking soda directly into the uncapped flask containing the vinegar. The provided image illustrates the experiment undertaken by Group 2.

What would be the anticipated difference between the final mass in Group 2's experiment when compared to that of Group 1's experiment, and what accounts for this outcome?

Responses

The concluding mass in Group 2's experiment is expected to exceed that of Group 1's experiment due to the ingress of gas from the surrounding environment, augmenting the final mass.

The ultimate mass in Group 2's experiment is expected to equal the final mass in Group 1's experiment, as mass remains conserved throughout chemical reactions.

The concluding mass in Group 2's experiment is anticipated to be lower than that in Group 1's experiment, as gas is permitted to exit the flask, leading to a reduction in the final mass.

The concluding mass in Group 2's experiment is projected to surpass the final mass in Group 1's experiment, as mass is invariably augmented during chemical reactions.

Answer 1

The ultimate mass in Group 2's experiment is expected to equal the final mass in Group 1's experiment, as mass remains conserved throughout chemical reactions.

Explanation: In both Group 1 and Group 2, the same total mass of reactants (5 grams of baking soda and 25 grams of vinegar) is used, and the chemical reaction that takes place between baking soda and vinegar produces carbon dioxide gas. In Group 1, the gas produced is trapped in the balloon, while in Group 2, the gas escapes into the environment. However, regardless of whether the gas is contained or allowed to escape, the law of conservation of mass states that the total mass of the system before and after the reaction remains constant. Therefore, the final masses of the two groups will be the same.
