Radioactive copper-64 decays with a half-life of 12.8 days. a. What is the value of k in s^-1? b. A sample contains 28.0 mg 64Cu. How many decay events will be produced in the first second? Assume the atomic mass of 64Cu is 64.0. c. A chemist obtains a fresh sample of 64Cu and measures its radioactivity. She then determines that to do an experiment, the radioactivity cannot fall below 25% of the initial measured value. How long does she have to do the experiment?
Describe the type of common chemical hazards that are present in your local environment, similar to those illustrated in the Tox Town interactive.
