The half-life of 82 35Br is 1.471 days. This isotope decays by the emission of a beta particle. a Gaseous HBr is made with Br-82. When the bromine isotope decays, the HBr produces H2 and the bromine decay product. Write a balanced equation for the decay of Br-82. Now, write a balanced equation for the decomposition of H82Br. b If a pure sample of 0.0150 mol of HBr made entirely with Br-82 is placed in an evacuated 1.00-L flask, how...

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...
