Ch31 P34 A rare decay mode has been observed in which 222 Ra emits a 14C nucleus The decay equation is 222 Ra AX 14C and you have identified unknown nuclide AX in the problem of Section 31 4 You ll need to use that answer in this problem a Find the mass change from the parent nuclide to the daughter nuclides Enter your answer to 7 SigFigs The mass change answers in nuclear decays must be correct to 6 places pas the decimal point Units are not required for this problem U b Find the energy emitted in the decay in units of MeV The mass of 222 Ra is 222 015353 u Enter your answer to 3sigFigs in MeV Units are not required in this answer
