Question

Cold packs are used to treat minor injuries. Some cold packs contain NH4NO3(s) and a small packet of water at room temperature before activation. To activate this type of cold pack, the small packet must be broken to mix the water and NH4NO3(s). The temperature of this mixture decreases to approximately 2°C and remains at this temperature for 10 to 15 minutes.

Identify both types of bonds in the NH4NO3(s).

Answer 1

all the information provided at the begining is supposed to help? or is it just trivia?
NH4NO3 has ionic bond (because NH4+ and NO3- are in fact ions that pull each other towards) and a bunch of covalent bonds between each atom in the ions.
