A chemistry student combines 23.0 grams of sodium and 71.0 grams of chloride to form sodium chloride. According to the law of conservation of mass, what mass of sodium chloride should be formed if the reaction proceeds to completion?

94.0 g.

Explanation:

Hello!

In this case, since the lay of conservation of mass states that energy cannot be neither created nor destroyed, during a chemical reaction it is seen that the reactions undergo a change by which bonds can be broken or formed depending on the case. Thus, for the formation of sodium chloride we evidence the formation of the Na-Cl bond which means sodium is combined with chlorine according to the following chemical reaction:

It means that the reuslting mass of product is:
