The question is incomplete, the complete question is;
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:
C) equal to the total mass of the products.
Explanation:
The law of conservation of mass states that, in a given chemical reaction, mass can neither be created nor destroyed.
The implication of that is; the mass of reactants in a given chemical reaction must also be equal to the mass of the products.
For this given reaction, the mass of reactants is equal to the mass of the products since mass is neither created nor destroyed.
