answered-by-expert Expert Answer

Chemical Reaction:

  • A chemical reaction is a process in which the initial substances change to form a new substance.
  • Chemical reactions involve chemical changes.
  • During chemical reactions, a rearrangement of atoms takes place between the reacting substances to form a new substance having entirely different properties.
  • Chemical reaction involves breaking of old chemical bonds existing between the atoms of reacting substances, and then making of new chemical bonds between the rearranged atoms of new substances.
  • During a chemical reaction, the atoms of one element do not change into those of another element. Only a rearrangement of atoms takes place in a chemical reaction.
