User: In terms of energy, how would you classify the following chemical reaction? 2Cu + O2 ? 2CuO + 315 kJ A. endothermic B. exothermic C. both endothermic and exothermic D. neither endothermic nor exothermic

Weegy: exothermic: 1. release heat, therefore the room temperature will increase 2. ?H = negative (kJ mol^-1) 3. [ [ bond will be formed, and energy will be release in form of heat, the molecules that are formed had a lower kinetic energy but very stabil endothermic: 1. absorb heat, therefore the room temperature will decrease 2. ?H = positive (kJ mol^-1) 3. bonds will broke down, because the energy of reactants are less than the energy of products in the chemical reaction ] ]
