What is most likely to occur during a chemical reaction?

Question

A. New atoms are created
B. Atoms of the original substance are lost
C. The original substance maintains its properties
D. Mass is conserved

Answer 1

D. Mass is conserved

In a chemical reaction, the mass of the reactants is equal to the mass of the products, meaning that mass is conserved. Atoms rearrange to form new substances, but no atoms are created or lost, and the original substances do not maintain their properties after the reaction.
