Calculate the energy (MeV) liberated in the decay of U-238 to produce Th-234 if the mass of U-238 = 238.050786 amu, Th-234 = 234,043583 amu, and He-4 = 4.002603 amu. If 40 grams of 90Th-234 produced from the decay of U-238 decays, it emits -rays and - rays with a half-life of 24 days. Determine the radionuclide X formed in this decay, and also calculate how many moles of 90Th-234 remain after 96 days of standing.

Dr. X claims that she has found a new remedy (carrot extract) to cure acne. She scores an interview with the science writer for a local newspaper, and gets a brief article written about her and her claims in that newspaper. The article does not contain any experimental evidence, but mentions that Dr. X accidentally splashed some carrot extract on her face and found that the acne was reduced a few days later. Student Y finds the article and cites it as a source for a paper he is writing for class, as evidence that acne has been cured. (a) Is this finding a fact, a theory, a hypothesis, or an observation? Explain why you think so. (b) Was it OK for Student Y to use the newspaper article as evidence for his paper? Explain why or why not.
