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.

1 answer

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.
