Some of the mass has escaped as a gas.
Some of the mass has escaped as a gas.

Some of the mass was destroyed during the reaction.
Some of the mass was destroyed during the reaction.

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

There is no way the mass can be different.

Answer 1

The correct statement that explains the observation is:

Some of the mass has escaped as a gas.

This is because during the reaction between vinegar (acetic acid) and baking soda (sodium bicarbonate), carbon dioxide gas is produced, which can escape into the atmosphere, leading to a lower mass after the reaction compared to the mass before the reaction.

The other statements either contradict the principles of conservation of mass or do not accurately describe the observation.
