Determine how much energy is released when polonium 210 decays according to Po He. Atomic masses,...
Polonium-210, 210Po, decays to lead-206, 206Pb, by alpha emission according to the equation 210 Po 206Pb + He 84 If the half-life, t 112, of 210 Po is 138.4 days, calculate the mass of 206 Pb produced from a 562.0 mg sample of polonium(IV) chloride, PoC14, that is left untouched for 334.1 days. Assume that the only polonium isotope present in the sample is the 210 Po isotope. The isotopic molar masses of 210 Po is 209.98 g/mol and 206Pb...

Use Conservation of Mass-Energy to determine how much kinetic energy is released when Radium-224 decays into Radon-220 and Helium-4 (an alpha particle). The relevant masses are mRa = 224.020186u, mRn = 220.011368u, and mHe = 4.002603u. Kinetic energy released: A Uranium-236 nucleus that is initially at rest has a mass of 2.9e-25 kg and is initially at rest. When it decays, it creates two fragments that fly off in opposite directions. Fragment #1 moves to the left at a velocity...
