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 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 exothermic; heat energy has been released to the air, leaving the products cold.

The correct response is:
**It is endothermic; heat energy has been removed from the surroundings, making the flask cold.**
This indicates that the process absorbs heat from the surroundings (the water and the flask) in order to dissolve ammonium nitrate, resulting in a decrease in temperature and making the flask feel cold.
