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

answers:

Law of conservation of mass. Mass cannot be created nor destroyed

Some of the mass was destroyed during the reaction

There is no way the mass can be different

Some of the mass has escaped as a gas

Answer 1

The two statements that explain the observation that the total mass after the compounds react is less than the sum of the masses before they react are:

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

These statements support the idea that the reaction's products can include gases that may escape from the system, resulting in a lower measured mass after the reaction.
