q1 When ammonium nitrate is dissolved in water in a glass container, the glass container becomes cold. Is this an endothermic or exothermic reaction? How do you know?
a
It is exothermic; heat energy has been released to the surroundings, leaving the container cold.
b
It is endothermic; heat energy has been released to the surroundings, leaving the container cold.
c
It is exothermic; heat energy has been removed from the surroundings, making the container cold.
d
It is endothermic; heat energy has been removed from the surroundings, making the container cold.
i think q2 is exothermic
The answer to this question is option c: It is exothermic; heat energy has been removed from the surroundings, making the container cold.
To determine the answer, you need to understand the concept of endothermic and exothermic reactions and the fact that the dissolution of ammonium nitrate in water is an exothermic process.
An exothermic reaction is a chemical reaction in which energy is released to the surroundings. In this case, when ammonium nitrate is dissolved in water, energy is released in the form of heat. This energy is transferred from the chemicals to the surrounding environment, causing the glass container to become cold.
On the other hand, an endothermic reaction is a chemical reaction that absorbs energy from the surroundings. In an endothermic reaction, the container would actually become warmer as heat energy is taken in from the surroundings.
Therefore, since the container becomes cold when ammonium nitrate is dissolved in water, it indicates an exothermic reaction, where heat energy is removed from the surroundings, making the container cold. Hence, option c is the correct answer.
