While dissolving 80.0 g of ammonium nitrate in 50.0 mL of water at room temperature, you observe that the temperature of the solution
decreases by 5.0°C and the vessel feels cold to the touch. You
realize that the formation of the solution must be an endothermic
process!

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
