Question 19 Massive stars are capable of fusion reactions involving elements that are heavier than Hydrogen and Helium. Very massive stars will eventually undergo Carbon Burning, where Carbon fuses into heavier elements. One such reaction is 2C+¹2CNa + H+ y Assume the masses of the various reactants and produces are as shown below: Mass of ¹2C 1.99265 x 10-26 kg Mass of Na = 3.81754 x 10-26 kg Mass of H= 1.67377 x 10-27 kg a. [2] Determine the mass defect for this process. b. [2] Based on your answer for part a, state whether energy is emitted or absorbed by this reaction. Please explain your answer. c. [2] Calculate the energy absorbed or released during the reaction, and express your answer in MeV. Total: 6 Marks
