The best description of a chemical reaction is "forming or breaking bonds." Chemical reactions involve the rearrangement of atoms to form new substances. This typically occurs through the breaking and formation of chemical bonds between atoms.
To determine the best statement among the given options, we can eliminate repetitive choices and focus on the unique descriptions. Out of the four options provided, "forming or breaking bonds" is the most accurate and comprehensive way to describe a chemical reaction.
Keep in mind that chemical reactions can involve mixing two substances, the decomposition of particles, or the combustion of a substance, but these descriptions are not as fundamental as the formation or breaking of chemical bonds.
