Answer:
The addition of energy through the chemical reaction when substance combines and gets decomposed.
Explanation:
- Chemical changes take place when the substance combines with some other to form a chemical synthesis and gets alternatively decomposed into 2 different substances through chemical reactions.
- As when the chemical reactions occur the atoms rearrange themselves. As these are accompanied by the energy changes.
- Such as those of sodium and water to produce sodium hydroxide and hydrogen. The chemical changes are found in organic, inorganic, and biochemical changes.
