According to Lavoisier's law, in the given reaction the mass of zinc produced will be 104 g.

Let's consider the following reaction.

Ca    +    ZnCO₃    ⇒    CaCO₃    +    Zn

64g         192 g              152 g           ? g

<h3>What does Lavoisier's law state?</h3>

Lavoisier's law states that the sum of the masses of the reactants before the reaction is equal to the sum of the masses of the products after the reaction.

mCa + mZnCO₃ = mCaCO₃ + mZn

mZn = mCa + mZnCO₃ - mCaCO₃

mZn = 64 g + 192 g - 152 g = 104 g

What would be the amount of zinc formed during the reaction?

  • The mass of zinc produced will be 104 g. TRUE.
  • The mass of zinc will be the same as that of zinc carbonate. FALSE.
  • The mass of zinc produced will be 52 g. FALSE.
  • The mass of zinc will be the same as that of calcium. FALSE.

According to Lavoisier's law, in the given reaction the mass of zinc produced will be 104 g.
