The number of atoms of all the elements on both sides of the reaction equation are the same hence matter is not created or destroyed.
Let us begin by saying that matter can neither be created nor destroyed but it can be transformed from one form to another. We call this the law of the conservation of mass and it is well established in science.
In a chemical reaction, the law of the conservation of mass is strictly followed. This is manifested in the fact that the total mass before the reaction is still the total mass before the reaction.
As such, the total number of atoms on the left hand side of the reaction must be equal to the total number of atoms on the right hand side of the reaction.
We can see that there are eight oxygen atoms on both sides of the reaction equation and this can be demon started for all the atoms shown here.

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:
In order to show that matter is neither created nor destroyed, the reactant side needs to be equal to the number of atoms of the product side.
