Question

Which of the following chemical equations best describes the dissolution of ammonium nitrate in water?

a. NH4NO3(s) ==> NH4NO3(aq);b. NH4NO3(s) ==> NH4+(aq) + NO3-(aq);c. 2 NH4NO3(s) ==> 2 N2(g) + 4 H2(g) + 3 O2(g

Answer 1

The correct answer is letter b. NH4NO3(s) ==> NH4+(aq) + NO3-(aq)

Step-by-step explanation:

It is not the letter A because the compound is ionic so should dissociate into ions. Also, it is not the letter C because the dissolution is a physical process, thus the compound should not undergo a chemical reaction.
