Explain the theory behind carbon-14 dating. What assumptions must be made and what problems arise when using carbon-14 dating?
Answer to relevant QuestionsThe decay of uranium-238 to lead-206 is also used to estimate the age of objects. Specifically, 206Pb-to-238U ratios allow dating of rocks. Why is the 238U decay to 206Pb useful for dating rocks but useless for daring ...A rock contains 0.688 mg of 206Pb for every 1.000 mg of 238U present. Assuming that no lead was originally present, that all the 206Pb formed over the years has remained in the rock, and that the number of nuclides in ...The mass defect for a lithium-6 nucleus is —0.03434 g/mol. Calculate the atomic mass of lirhium-6. Much of the research on controlled fusion focuses on the problem of how to contain the reacting material. Magnetic fields appear to be the most promising mode of containment. Why is containment such a problem? Why must one ...The mass percent of carbon in a typical human is 18%, and the mass percent of 14C in natural carbon is 1.6 X 10-10%. Assuming a 180-lb person, how many decay events per second occur in this person due exclusively to the ...
