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.
