Answer:
104g
Step-by-step 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
