Question

question 5: 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? a the mass increase b the mass decrease c the mass remains constant d the mass first decreases and then increases

Explanation:

According to the law of conservation of mass, in a chemical reaction, the total mass of the reactants equals the total mass of the products. Here, silver nitrate ($AgNO_3$) and sodium chloride ($NaCl$) react to form silver chloride ($AgCl$) and sodium nitrate ($NaNO_3$), but the total mass remains the same.

Answer:

C. The mass remains constant
