The total number of molecules before and after a chemical reaction stays the same.
The total number of molecules before and after a chemical reaction stays the same.
Atoms created during a chemical reaction must have the same mass as the atoms in the reactants.
Atoms created during a chemical reaction must have the same mass as the atoms in the reactants.
New molecules cannot be formed from the reactants during a chemical reaction.
The total mass of the reactants is equal to the total mass of the products.

The answer that is always true according to the Law of Conservation of Matter is:
The total number of molecules before and after a chemical reaction stays the same.
To understand why this is true, we need to understand the Law of Conservation of Matter. This law states that matter cannot be created or destroyed in a chemical reaction; it can only be rearranged. In other words, the total amount of matter before a reaction is equal to the total amount of matter after the reaction.
To determine the answer to this question, we can consider the fact that molecules are made up of atoms. During a chemical reaction, atoms can be rearranged to form new molecules, but the total number of atoms before and after the reaction remains the same. Therefore, the total number of molecules also stays the same.
By considering the Law of Conservation of Matter and understanding that atoms can be rearranged but not added or taken away during a chemical reaction, we can conclude that the total number of molecules before and after the reaction remains unchanged.
