Question

On a balance, you have beakers of AgNO3 A g N O 3 solution and NaCl N a C l solution. When mixed, they will form AgCl(s) A g C l ( s ) . What will happen to the mass of the new mixture?

Answer 1

It remains the same.

Step-by-step explanation:

From the law of conservation of mass which states that mass in an isolated system can neither be created nor destroyed in a chemical reaction.

According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants, that is total mass of the system is unchanged after the chemical reaction.

So therefore, the reaction of

AgNO3(aq) + HCl(aq) --> AgCl(aq) + HNO3(aq)

the mass of the solution before and after the reaction is unchanged.
