The hydride of an unstable nuclide of a Group IIA metal, MH2(s), decays by a-emission. A 0.025-mol sample of the hydride is placed in an evacuated 1.1 −L container at 298 K. After 64 minutes, the pressure in the container is 0.49 atm. Find the half-life of the nuclide. Express your answer to two significant figures and include the appropriate units.
Please show your steps clearly.
. The radioactive isotope Uranium-234 decays to Thoriu-230 with a half-life of T. Thorium 230 itself is also radioactive and decays to Radium-226 with a half-life of γ and γ > τ Although Radium-226 is also radioactive its half-life is much longer than T and γ and here we assume that it is relative stable. Consider the scenario when we start with a certain amount of pure Uranium-234, because of this chain of decays, we...
