Write out a balanced chemical equation for 241Am undergo

12

Potassium (Z = 19) has three primary isotopes: K-39, K-40, and K-41 a. Determine the most likely type of nuclear decay that K-40 undergoes and write the balanced nuclear equation for one of these decays. b. Potassium-argon (K-Ar) dating is commonly used to determine the age of a sample by measuring the amount of Ar-40 present which was produced by the radioactive decay of K-40. Write the balanced nuclear reaction to show how K-40 becomes Ar-40.

a) Mrs. Price's son, Liam is currently working as a boilermaker at the Darlington Nuclear Power plant. He is working with Uranium-237 which has a half-life of 13.75 days. What mass of an initial sample of 567.5g of uranium-237 would remain after 56 days? b) Write the complete reaction for the decay of Po-210 if it undergoes 2 consecutive alpha decay followed by a beta decay followed by another alpha decay.

a. Write the nuclear equation for the alpha decay of ^221-81Rn. b. Write the nuclear equation for the radioactive decay of ^21-15P by positron emission. c.  Imagine that you started with a 0.1 g sample of iodine-131, and now you have only 0.025 g remaining. If the half-life of iodine-131 is 8 days, how old is the sample? Write 2 - 3 sentences explaining your reasoning. d. Draw a diagram that illustrates how nuclei change during nuclear fusion. Write 2 - 3 sentences describing the process of nuclear fusion, including where it occurs and how the energy released can be harnessed for use in homes.
