ENDOTHERMIC
During this chemical reaction energy is absorbed. In the chemistry lab, this would be indicated by a decrease in temperature or if the reaction took place in a test tube, the test tube would feel colder to the touch. Reactions like this one absorb energy because
The reactants have less potential energy than the products.
