Instant cold packs contain solid NH4NO3 and a separate pouch of water. When the pack is squeezed, the pouch breaks and the solid dissolves in the water. The energy change due to the dissolving process affects the aqueous solution: NH4NO3(s)NH4(aq)+NO3(aq)H=25.7kJ Consider what happens when a cold pack containing 50.0gNH4NO3 and 125 g water is squeered. a) Is heat released or absorbed by the dissolv neprocess? How do you know? b) Hgw much heat (in kJ) is released or abcorbed by this dissolving process? c) What is the final temperature of the solution in the pack? (Assume mass =175g, Cooknon = 4.18d/BC. initial temp =25.0C and a well insulated system) Pleage write out all your calculations and submityour answer as a fle upload. (pdi,jpeg, doc. heicl
