Nuclear reactions
Nickel-56 decays with a half-life of 6.075 days.
1. Write the balanced nuclear reaction of Ni-56 as it undergoes positron emission.
2. Determine the decay constant of the radioactive decay of Ni-56.
3. How long does it take for a sample of Ni-56 to decay to 2.00% of its original mass?
After 5.69 hours, a radioactive nuclide has passed through exactly five half-lives. The initial amount of the radioactive nuclide is 15.8912 grams.
1. Compute for the remaining amount (in grams) of the radioactive nuclide after the given time.
2. Calculate the rate constant (in hr -1) of the decay of the radioactive nuclide.
