When magnesium hydroxide reacts with nitric acid, it produces magnesium nitrate and water. 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:

The law of conservation of mass states that mass is neither created nor destroyed but the mass of the system must remain constant over time. The total number of atoms in the reactants is equal to the total number of atoms in the product. Therefore, this chemical equation shows that energy is conserved and demonstrates the law of conservation of mass.

To demonstrates that matter is neither created nor destroyed in the chemical reaction the number of atoms or masses in the reactant sides must be equal to the number of atoms or masses of the product side.

The law of conservation of masses states that masses are neither created nor destroyed but can be transformed from one form to another.

In a chemical reaction, it simply means the masses of the reactant will be equal to the masses of the product.  

For a chemical equation to obey law of conservation of mass, the equation must be balanced. Therefore,

Mg(OH)₂ + 2HNO₃ → Mg(NO₃)₂ + 2H₂O

Therefore, to demonstrates that matter is neither created nor destroyed in the chemical reaction the number of atoms or masses in the reactant sides must be equal to the number of atoms or masses of the product side.
