Explain Instant cold packs, frequently used to ice athletic injuries on the field, contain ammonium nitrate as well as water separated by a thin plastic divider. Explain when the divider is broken, the ammonium nitrate dissolves as per to the following endothermic reaction
NH4NO3 (s)--->NH4+NO3-(both aq).

In order to compute the enthalpy change for this reaction, 1.25 g of NH4NO3 is dissolved in sufficient water to make 25.0 mL of solution. The preliminary temperature is 25.8 C as well as the final temperature (after the solid dissolves) is 21.9 C.

Compute the change in enthalpy for the reaction in kJ.

Utilize 1.0 g/mL as the density the solution & 4.180 J/g xC as the specific heat capacity
