Chapter 19, Problem 44R

To determine

To explain: The type of the law that demonstrated by the Lavoisier’s experiment.

Answer to Problem 44R

The right answer is option D − Law of conservation of mass.

Explanation of Solution

Introduction:

According to the law of conservation of mass, matter can never be created nor be destroyed in a chemical reaction, it remains the same in a chemical reaction.

In the given experiment, Lavoisier experimented with the mercury oxide and heat. In this experiment, he found that the mass of product becomes equal to the mass of reactants which means that this reaction follows the law of conservation of mass.

Conclusion:

Thus, the experiment given in the photograph follows the conservation law of mass.
