1. The law of conservation of mass states that the mass of anything that includes the transferring of energy or matter, must remain the same or constant over a period of time. This lab shows the conservation of mass because when we first weighed the beakers separately, one with Vinegar and the other with Baking soda, and also weighed them together, there was not a great change compared to the initial mass. Instead, the mass of both Vinegar and Baking soda weighed less than they did separately.

2. From this reaction, we assume that the mass was lost from the initial mass to our final mass because gas was released. The beaker did not keep the mass because it was open. Therefore, gas was released into the air when both the vinegar and Baking soda made a reaction.

3. The evidence that can be shown to prove that mass is conserved and that our assumptions are valid include the effect that was caused by the vinegar and the baking soda. When the baking soda was poured into the vinegar, it bubbled which was an indication that gas was being held in the bubble and when it popped, the gas that was inside the bubble was released into the air. If we had a closed container than the mass might have been slightly different.
