which best describes a chemical reaction?\n the rearrangement of atoms by breaking and reforming chemical bonds\n a reaction that absorbs heat from the surroundings\n a reaction that releases heat to the surroundings\n the rearrangement of molecules based on temperature and pressure
Answer
Brief Explanations:
A chemical reaction involves the breaking and forming of chemical bonds to rearrange atoms. Endothermic reactions absorb heat and exothermic ones release heat, but these are just types of reactions. Rearrangement based on temperature - pressure is more about physical changes in some cases. The core of a chemical reaction is bond - breaking and atom - rearrangement.
Answer:
the rearrangement of atoms by breaking and reforming chemical bonds
