Which of the following is not true about the law of conservation of mass? a) nothing is created. b) the same number of atoms are in both the products and the reactants. c) new atoms are created when a new substance is formed. d) nothing is destroyed.

C) New atoms are created when a new substance is formed.

Explanation:

The mass conservation law was created by Antoine Lavoisier states that "in nature, nothing is lost, nothing is created and everything is transformed". This law stated that within a system where a chemical reaction occurs, the mass becomes a constant quantity, that is, the mass at the beginning of the reaction must be the same at the end of the reaction. This is because the number of atoms present in the reagents must be exactly the same as the number of atoms present in the product.

With that, we can affirm that the law of conservation of masses, affirm that in nature nothing is created, nothing is destroyed and the same number of atoms is in the products and in the reagents. However, this law denies that new atoms are created when a new substance is formed.
