Most first aid "cold packs" are based on the dissociation of ammonium nitrate (NH4NO3) in water. When the cold pack is activated, the ammonium nitrate (NH4NO3) dissolves in water, producing ammonium (NH4+) and nitrate (NO3-) ions. The "cold pack" then feels cold to touch. What conclusion can be drawn about the bond energy of products and reactants?
A) More energy was absorbed in the formation of chemical bonds than released in the breaking of chemical bonds.
B) Less energy was absorbed in the breaking of chemical bonds than released in the formation of chemical bonds.
C) More energy was absorbed in the breaking of chemical bonds than released in the formation of chemical bonds.
D) Less energy was absorbed in the formation of chemical bonds than released in the breaking of chemical bonds.
