What is always true according to the Law of
Conservation of Matter? (1 point)
Atoms can be rearranged during a
chemical reaction but cannot be added
or taken away.
New molecules cannot be formed from
the reactants during a chemical reaction.
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 can be rearranged during a
chemical reaction but cannot be added
or taken away.
According to the Law of Conservation of Matter, the answer is: "The total number of molecules before and after a chemical reaction stays the same."
The Law of Conservation of Matter states that matter cannot be created or destroyed during a chemical reaction, but it can be rearranged. This means that the total number of atoms and molecules must remain constant. So, no atoms can be added or taken away, and new molecules cannot be formed from the reactants. The atoms that are present before the reaction must also have the same mass as the atoms in the reactants. In summary, while atoms can be rearranged, the total number of molecules before and after a chemical reaction stays the same.
