3. Which of the following is the best description of a chemical reaction? O A. When molecules of a substance move slowly enough, they link together to form a crystalline structure. B. When two molecules collide with enough force, old chemical bonds are broken and new bonds form, resulting in one or more new substances. O C. When two molecules collide with enough force, they shatter into individual atoms. Later, these atoms join up in new combinations to form new substances. O D. When two atoms collide with enough force, their nuclei fuse together, forming new substances and releasing tremendous amounts of energy.
