The number of unstable nuclei remaining after a time t 5.00 yr is N, and the number present initially is N0. Find the ratio N/N0 for (a) (half-life 5730 yr), (b) (half-life 122.2 s; use t 1.00 h, since otherwise the answer is out of the range of your calculator), and (c) (half-life 12.33 yr).

Review | Constants Periodic Table In the parts that follow, use the following abbreviations for time If a substance is radioactive, this means that the nucleus is unstable and will therefore decay by any number of processes (alpha decay, beta decay, etc.). The decay of radioactive elements follows first-order kinetics. Therefore, the rate of decay can be described by the same integrated rate equations and half-life equations that are used to describe the rate of first-order chemical reactions: Measure of...

Calculate the percent activity of the radioactive isotope iridium-192 remaining after two half-lives. activity: While exploring a coal mine, scientists found plant fossils which had been preserved by an earthquake in the ceiling of the mine. Samples taken from one of the fossils had carbon-14 activities of 40.0 counts/min. A reference sample of the same size from a plant alive today has a carbon-14 activity of 160.0 counts/min. If carbon-14 has a half-life of 5730 years, what is the age...

Rules of the leprechaun world The game starts out with n leprechauns. Each leprechaun starts out with a million dollars of gold (i.e., gi = 1,000,000). The player wants to trap as many of these leprechauns in a pit and steal their gold! The leprechauns are all in a row, with each leprechaun at location xi, a double precision floating point number. Initially, the first leprechaun is at x=0, the second at x=1000, the third at 2000, ...; i.e., xi...
