Question

Classify the reaction as endothermic or exothermic. Select the single best answer.

exothermic

endothermic

cannot be determined

Answer 1

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)

Answer 2

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.

Answer 3

Yes, that is correct. In an exothermic reaction, heat is released to the surroundings, resulting in a decrease in the energy of the system. This can be observed as an increase in temperature, so the reaction is classified as exothermic.
