Question

cca 1 retest (8.6abe)
two solutions are mixed and react to produce the solid precipitate agcl. the chemical reaction is shown by the balanced chemical equation.
agno₃ + nacl → agcl + nano₃
what happens to the total mass as the reaction takes place?
the mass increases.
the mass decreases.
the mass remains constant.
the mass first decreases and then increases.

Explanation:

According to the law of conservation of mass, in a chemical reaction, the total mass of reactants equals the total mass of products. Here, the reactants are AgNO₃ and NaCl, and the products are AgCl and NaNO₃. No mass is created or destroyed during the reaction.

Answer:

The mass remains constant.
