Mg(OH)2 + 2HNO3 -> Mg(NO3)2 + 2H2O

In one to two sentences, explain how this reaction demonstrates that matter is neither created nor destroyed in a chemical reaction.

Answer 1

This reaction demonstrates the law of conservation of mass as the total number of atoms of each element remains the same on both sides of the chemical equation, indicating that no new atoms are created or destroyed during the reaction.

Answer 2

This reaction demonstrates the law of conservation of mass, as the total number of atoms of each element on both sides of the chemical equation remains the same, indicating that no atoms are created or destroyed during the reaction.

Answer 3

This reaction demonstrates the principle of conservation of mass because the total number of atoms on both sides of the equation remains the same, indicating that no atoms are created or destroyed during the reaction.
