Question

Cosmic rays are mostly high energy protons. They often fragment thenuclei in the earth's atmosphere with which they collide, releasingmany neutrons. These react with Nitrogen to make Carbon-14, whichis radioactive. The reaction is
14N +n 14C + 1H+ energy Calculate the energy released in the reaction. Mass Data:14N: 23.252668 × 10-27kg;14C: 23.252946 × 10-27kg; n:1.674929 × 10-27kg 1H:1.673534 × 10-27kg.

I have absolutely no idea what this is asking me. It's mylast question, due soon! Please help, and thanks!
14N +n 14C + 1H+ energy

Explanation / Answer

23.252668 1.674929 24.927597       adding the masson the left side of the equation 23.252946 1.673534 24.926480     adding the mass on the rightside of the equation M = .001117  * 10E-27    differenceof mass which has been converted to energy (sometimes called "massdefect") E(nergy) = M c2 = .001117 * 10E-27 * (3 *10E8)2 = 1.0053 * 10E-13 J Or 6.28 * 10E5 eV = .628MeV      (1 eV = 1.6 * 10E-19 J)
