Question

The table shows mass and volume measurements in an investigation that involves vinegar and baking soda, both before and after the chemical reaction.

What evidence supports the law of conservation of mass?

The mass remains constant before and after the chemical reaction
The volume of the products is more than the volume of the reactants, so it does not support the law of conservation of mass.
The mass of the gas is more than the mass of the baking soda, so the mass is constant
The density of the products is less than the reactants, so the mass is constant.

Answer 1

mass will be less

Step-by-step explanation:

A chemical reaction takes place when vinegar and baking soda are mixed. One of the new substances formed is carbon dioxide gas. If the carbon dioxide gas is contained, the mass of the substances will stay the same according to the Law of Conservation of Mass. If the gas is allowed to escape, the mass will be less
