Carbon-14 decays as follows: 14 0 14 &

Carbon-14 decays as follows: 14 0 14 C ----> e + N 6 -1 7 isotopic masses are 14.00307 for nitrogen-14 and 14.00324 for carbon-14. What energy change (kJ/moles) occurs in the beta decay of C-14? NOTE: Do I use these two masses to get the mass defect or do I use the mass of protons and nuetrons to find the mass defect of each one and then subtract the two?

Carbon-14 dating

Carbon-14 dating works for fossils up to about 75,000 years old; fossils older than that contain too little 14C to be detected. Most dinosaurs went extinct 65.5 million years ago. (a) Can 14C be used to date dinosaur bones? Explain. (b) Radioactive uranium-235 has a half-life of 704 million years. If it was incorporated into dinosaur bones, could it be used to date the dinosaur fossils? Explain.

Carbon 14 (C-14), a radioactive isotope of carbon, has a half-life of 5730 ± 40 years. Measuring the amount of this isotope left in the remains of animals and plants is how anthropologists determine the age of samples. Example: The skeletal remains of the so-called Pittsburgh Man, unearthed in Pennsylvania, had lost 82% of the C-14 they originally contained. Determine the approximate age of the bones assuming a half-life of 5730. (a) 14,000 years (b) 15,000 years (c) 17,000 years...
