Question

The equation below shows the products formed when a solution of silver nitrate (AgNO3) reacts with a solution of sodium chloride (NaCl).


AgNO3 + NaCl → NaNO3 + AgCl

(Reactants) → (Products)


In this equation, the total mass of the reactants is
A) equal to the mass of AgCl.
B) less than the mass of AgCl.
C) equal to the total mass of the products.
D) greater than the total mass of the products.

Answer 1

I would say that the answer has to be C
Since there is no change in mols on both sides of the equation the mass is constant

Answer 2

C) igual a la masa total de los productos. equal to the total mass of the products.

In this equation, the total mass of the reactants is equal to the total mass of the products. This is in accordance with the law of conservation of mass.
