After a chemical reaction, some of the bonds have been broken, and some new bonds have been formed. So, that's how a substance is changed after the reaction.

Chemical reactions.
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
These substances are called reactants.
The substances that are changed in a chemical reaction are known as reactants. These reactants undergo a chemical change or transformation to form new substances called products through the rearrangement of their atoms.
Enzymes are special proteins that help change substances during chemical reactions by speeding up the reaction process without being consumed in the reaction.
Reactions can be both chemical and physical. Chemical reactions involve breaking and forming chemical bonds leading to the formation of new substances. Physical reactions involve changes in state, shape, or form of a substance without changing its chemical composition.
When one substance or combination of substances undergo change to become another substance or substances
Chemical reactions involve the breaking and forming of chemical bonds in the original substances, resulting in a chemical change. Before a chemical reaction occurs, the original substances have specific chemical properties that undergo transformation during the reaction. The reactants interact to form new products with different chemical compositions.
Oxidation rules determine how substances change in chemical reactions. These rules help identify which atoms lose or gain electrons, leading to the formation of new substances.
A key feature of a chemical change is the formation of new substances with different chemical properties from the original substances. This often involves the breaking and forming of chemical bonds.
