Both the statements are correct.
Explanation: A chemical reaction occurs when the bonds between the molecules of the reactant are broken and new bonds are created between the molecules of the product, resulting in the formation of new material.
When two or more molecules combine to form new products, this is referred to as a chemical reaction.
The breaking and creation of bonds in chemical reactions frequently result in energy shifts. Exothermic reactions are those in which energy is released, whereas endothermic reactions are those in which heat energy is taken in.
