Question

law of conservation of matter quick check
what is always true according to the law of conservation of matter? (1 point)
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.
new molecules cannot be formed from the reactants during a chemical reaction.
atoms can be rearranged during a chemical reaction but cannot be added or taken away.

Explanation:

The Law of Conservation of Matter states that matter is neither created nor destroyed in a chemical reaction. Atoms are just rearranged. Molecules can change (so new molecules can form and the number of molecules can vary). Atoms aren't created during a reaction (they are just rearranged from reactants).

Answer:

Atoms can be rearranged during a chemical reaction but cannot be added or taken away.
