According to the law of conservation of mass, how much zinc was PRODUCED by reacting Calcium and Zinc carbonate together?

104g

Explanation:

Based on the law of conservation of mass, the quantity of zinc produced by reacting calcium and zinc carbonate would be 104g.

The law of conservation of mass states that "in a chemical system, the mass is always conserved as matter is neither created nor destroyed but changed from one form to another".

 In short;

         Mass of products  = Mass of reactants

Mass of products  = Mass of CaCO₃ + Mass of Zn

Mass of reactants  = Mass of Ca + Mass of ZnCO₃

   So;

               152g + Mass of Zn = 64g + 192g

                           Mass of Zn  = 64g + 192g - 152g

                           Mass of Zn  = 104g
