Question

When ammonium nitrate is dissolved in water in a flask, the flask becomes cold. Is this an endothermic or exothermic reaction? How do you know?(1 point) Responses It is exothermic; heat energy has been released to the air, leaving the products cold. It is exothermic; heat energy has been released to the air, leaving the products cold. It is endothermic; heat energy has been released to the air, leaving the products cold. It is endothermic; heat energy has been released to the air, leaving the products cold. It is exothermic; heat energy has been removed from the surroundings, making the flask cold. It is exothermic; heat energy has been removed from the surroundings, making the flask cold. It is endothermic; heat energy has been removed from the surroundings, making the flask cold.

It is endothermic; heat energy has been removed from the surroundings, making the flask cold. This is because the dissolution of ammonium nitrate in water absorbs heat from the surroundings, causing the temperature of the flask to decrease.
