Chemistry: Principles and Reactions
- Describe how the potential energy of uranium is convened into electrical energy in a nuclear power plant.arrow_forwardWhich of the following elements has a radioactive isotope that is most commonly used in treating cancer through the radiation it gives off that kills the cancer cells?* Ra Co Which of the following elements is the best catalyst in catalytic converter, hydrogenation reaction, oxidation of ammonia and other reactions?" Palladium Platinum Ruthenium Nickel Which of the following characteristics islare common to the coinage metals? (a) They have high electrical and thermal conductivities. (b) They are the most ductile and malleable metals. (c) They all possess +1 oxidation states. (d) They are relatively unreactive. * a and b a, b, and c a, b, c, and d O O O Oarrow_forwardConsider the following: 48Ar; 98Rh; 190Os; 243Am Will all four undergo radioactive decay?arrow_forward
- If we start with L000 g of strontium-0, 0.953 g will remain after 2.00 yr. (a) What is the hal-life of strontium-07 (b) How much strontium-0 will remain after 5.00 yr? (c) What is the initial activity of the sample in Bq and in CI?arrow_forward11 C, used as a tracer in PET scans and C, used in dating organic materials are unstable isotopes of carbon. Calculate the N/Z ratio and write balanced spontaneous decay reactions for both atoms.arrow_forwardHow to write balanced equation to represent the decay for lead-214 (meta stable )arrow_forward
- 1) List 3 possible reasons why you might not observe a reaction even though the activity sreies indicates it should occur.arrow_forwardProvide the practical uses of the following: 1) Carbon 14 2) Uranium - 238 3) Iodine - 131 4) Cobalt - 60arrow_forward(7) Carbon-14 dating is used in archeology to determine the age of items that were alive or were made from living materials. This works because the proportion of radioactive Carbon-14 to the other isotopes of Carbon is relatively constant in the atmo- sphere. (Volcanos constantly refresh the C-14 content.) A wooden tool from an archeological site is found to contain 22 micrograms of C-14, whereas a similar hnount of modern wood would contain 100 micrograms. How old is the tool? 58 surface weat..pdf JoanneCarbonell .pdf PDFarrow_forward
- The elements of group 1 are reactive but those of griup 18 are inert, why?arrow_forwardRadioactive rhodium-99 decays with a half-life of 16.1 days. (a) What is the value of k in s-¹? S`1 (b) A sample contains 22.0 mg ⁹⁹Rh. How many decay events will be produced in the first second? Assume that the atomic mass of 99Rh is 99.0. decay events (c) A chemist obtains a fresh sample of 99Rh and measures its radioactivity. She then determines that to do an experiment, the radioactivity cannot fall below 25.0% of the initial measured value. How long does she have to perform the experiment? daysarrow_forward6. By what (single step) process does polonium-211 decay to lead-207?arrow_forward
