Answer:
The formation of an aqueous solution of ammonium nitrate is An endothermic process
Explanation:
An exothermic process produce energy when occurs. As there is energy that is released, the temperature of the arounds increases.
In the other hand, an endothermic process absorb energy when occurs doing the temperature of the around colder than the initial temperature.
As the dissolution of NH₄NO₃ in water make the temperature of the water colder:
The formation of an aqueous solution of ammonium nitrate is an endothermic process
The question requires us to determine if reaction process is an endothermic or an exothermic reaction.
To do this,
First we will define the terms Endothermic reaction and exothermic reaction
Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products. These reactions lower the temperature of their surrounding area, thereby creating a cooling effect. They have a net positive standard enthalpy change.
Exothermic reactions are reactions or processes that release energy, usually in the form of heat or light. They have a net negative standard enthalpy change.
From the question,
When solid NH4NO3 is dissolved in water, the temperature of the water and beaker gets noticeably colder. This means it is an endothermic reaction.
Hence, the formation of an aqueous solution of ammonium nitrate is an endothermic process
