AgNO3 and NaOH were combined in the first reaction. If you were to use a scale to find the mass of the AgNO3 and the NaOH before they were combined, and then find the mass of the final compound(s) after the experiment, how would the masses compare?

TLDR: They should be the same by the conservation law of masses.

Now it may appear as if they changed if one of the resulting products is in the form of a gas or another hard to examine and weigh. In those situations it may seem that the masses will change, but the ratio should remain constant. Try looking up 3.7: Conservation of Mass - There is No New Matter on ChemLibre for more information on this topic that goes more into depth about it.

If AgNO3 and NaOH are combined in a chemical reaction, the addition of the individual weights of the reactants must be equal to that of the compounds formed after the reaction.

Recall:

  • The law of conservation of mass states that mass can neither be created nor destroyed but can take different forms in reactions.

Looking at the equation of the reaction:

  • 2AgNO3 + 2NaOH ---> 2NaNO3 + Ag2O + H2O

There is no evolution of gas in the reaction. Hence, if a scale was used to find the mass of AgNO3 and NaOH before the reaction, the addition of the masses must be equal to the total mass of the compounds formed from the reaction.
