Question Review the model seen here. Select the best student description of the reaction. (1 point) Responses This reaction is endothermic because when the "cold pack" is squeezed it takes energy and that energy is released. This reaction is endothermic because when the "cold pack" is squeezed it takes energy and that energy is released. This reaction is endothermic. A "cold pack" where ammonium nitrate and water react can pull heat from the surroundings to the system so the pack feels cold. This reaction is endothermic. A "cold pack" where ammonium nitrate and water react can pull heat from the surroundings to the system so the pack feels cold. The reaction is exothermic since the "cold pack" is squeezed until it bursts. The reaction is exothermic since the "cold pack" is squeezed until it bursts. This reaction for an emergency "cold pack" represents an exothermic reaction because ammonium nitrate and water mix when the pack is squeezed.
