a chemical reaction a temperature change may occur because of the breaking or formation of chemical bonds that release excess energy. Since there is a change in temperature why wouldn't this reaction be considered a physical change instead of a chemical change ?

Respuesta :

Answer:

Explanation:

in some reactions we see this as a change in the temperature. ... The study of energy changes (particularly heat) in chemical reactions is known as ... When a chemical reaction occurs, bonds in the reactants break, while new bonds form in the product. ... Physical changes can also be classified as exothermic or endothermic.
