Using the same image of the vinegar and baking soda chemical reaction... A scientist finds that the total mass after the compounds react, is less than the sum of the masses before they react. Which 2 statements explain this observation.

Question

(1 point)

Some of the mass has escaped as a gas

Some of the mass was destroyed during the reaction

Law of conservation of mass. Mass can not be created nor destroyed

There is no way the mass can be different

Answer 1

The two statements that explain the observation of less mass after the reaction are:

1. Some of the mass has escaped as a gas.
2. Law of conservation of mass. Mass cannot be created nor destroyed.

These statements indicate that while mass is conserved in a closed system, if gas escapes during the reaction, it can lead to a measurable decrease in mass in the remaining materials.
