A chemical reaction involves the rearrangement of atoms to form new molecules. During a chemical reaction, however, atoms are neither created nor destroyed.

Which of the following is true about the atoms involved in a chemical reaction?
The total mass of the atoms involved in a chemical reaction always changes as the atoms are rearranged into new molecules.

The total mass of the atoms involved in a chemical reaction will decrease if two molecules combine to form one single compound.

Falconmaster · Answer

The total mass of the atoms involved in a chemical reaction will stay the same no matter how the atoms are rearranged.

The total mass of the atoms involved in a chemical reaction will increase if a new compound is formed during the reaction
