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.
