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...

If a radioactive isotope has half-life h, then the number of atoms in a sample is given by a(t)=a-2-/h where ao gives the number of atoms in the sample at time 0. The radio active decay of carbon-14 leads to clever way of determining the age of fossils and remnants of plants and animals. When an organism dies, the radioactive carbon- 14 in it decays, with half of it gone in 5,730 years. a. Suppose a mummified cat has a...
