Two solutions are mixed and react to produce the solid precipitate AgCl. The chemical reaction is shown by the balanced chemical equation below.



AgNO3 + NaCl --> AgCl + NaNO3



What happens to the total mass as the reaction takes place?

The mass increases.

The mass first decreases and then increases.

The mass decreases.

The mass remains constant.

The mass remains constant. This is because in a closed system, mass is neither created nor destroyed during a chemical reaction. The total mass of the reactants will be equal to the total mass of the products.
