Classify the reaction as endothermic or exothermic. Select the single best answer.
exothermic
endothermic
cannot be determined
Since the reaction is classified as either exothermic or endothermic based on the energy change during the reaction, it cannot be determined without knowing specific details or data about the reaction.
If it spews out heat it loses energy and is exothermic. (for example burning a log)
(the reactants Carbon and Oxygen lost energy as heat in the exothermic reaction)
