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 Change
chemical reactions
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.
Substances are changed only after the beginning of a chemical reaction.
These substances are called reactants.
When one substance or combination of substances undergo change to become another substance or substances
Substances that undergo chemical change are called reactants.
IT ACCELATATES THE CHEMICAL REACTIONS
Lysosomes have a chemical that breaks down foreign objects and substances.
Catalysts accelerate chemical reaction. Enzymes are examples of catalysts that speed up reactions in the body.
Reactants are substances that are changed when they become involved in chemical reactions. Products are the new substances that are formed.
