Detailed explanation-1: -Concluding Statement:-During chemical change, a substance undergoes a change in its chemical composition or change in chemical properties. Therefore, the properties of new substances formed in chemical changes are entirely different from those of the original substances.
Detailed explanation-2: -In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change.
Detailed explanation-3: -During a chemical reaction, the chemical properties of substances are changed to result in different chemical substances. A chemical reaction is characterized as the rearrangement of atoms to result in a chemical substance. In the reaction, old chemical bonds between atoms are broken and new chemical bonds are formed.
