Fluorine-18 is often introduced into specific drug molecules for use as imaging agents. a. Write a balanced nuclear equation for the decay of 18F. b. Calculate the binding energy for 18F. The exact mass of 18F is 2.98915 3 10226 kg.

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

Answer (b) supersaturation;
