Which best describes a chemical reaction? the rearrangement of atoms by breaking and reforming chemical bonds a reaction that absorbs heat from the surroundings a reaction that releases heat to the surroundings the rearrangement of molecules based on temperature and pressure

The answer is the rearrangement of atoms by breaking and reforming chemical bonds.

The process of chemical reaction involves the interaction between the atoms and molecules of the participating reactants and enzymes. The chemical bonds present within the molecules of the reactants undergo cleavage and rearrangement to form a new molecule of the product. Example, in the reaction of NaOH and HCl, the sodium atom gets separated from the hydroxide ion to combine with the chloride ion furnished by the dissociation of  HCl molecule.

The answer is the rearrangement of atoms by breaking and reforming chemical bonds.
