Dinitrogen trioxide, N2O3, is largely dissociated into NO and NO2 in the gas phase where there exists the equilibrium, N2O3 = NO + NO2 In an effort to determine the structure of N2O3, a mixture of NO and "NO2 was prepared containing isotopically labeled N in the NO2. After a period of time the mixture was analyzed and found to contain substantial amounts of both *NO and *NO2. Explain how this is consistent with the structure of N2O3 being ÔNONO. Because this is an equilibrium process, there is a change that either the forward or the reverse reactions will occur. As NO reacts with NO2 we form This compound can decompose and give either NO2 and and "NO2. or After sufficient time, v will be present in the mixture. both "NO and NO Attempts: 0 of 3 used Submit Answer Save for Later only *NO only NO
A tiny percent of all naturally-occurring carbon atoms on Earth are carbon-14. Trees (and all living things) incorporate C-14 into their bodies when alive, but this ceases at death, after which the amount of C-14 present gradually decreases due to nuclear decay. Wooden artifacts from long ago can be dated by the percent of carbon-14 remaining in them. A sample of a wooden object from an archaeological site contains only 12.5% of the level of carbon-14 expected for a live tree. How many half-lives have passed since that piece of wood was a living tree?
Kindly write the full solution on a paper, much obliged
The stable isotope of carbon is C-12. Predict the nuclear process for the decay of C-14.
3) Carbon-14 is constantly being produced in the upper atmosphere, and the amount is in equilibrium. As long as an organism is alive, it keeps its carbon isotopes in balance with the atmosphere, but at soon as it dies, it stops taking up new 14C, and so the geologic clock starts. You found a shell buried in sedimentary layers, which has 6% of its original 14C left. Determine the age of the shell. Show your work.
3. Plutonium 238 is a radioactive element that decays at a rate of 0.8% per year. (a) What percentage of an initial supply of 250 grams Plutonium 238 will remain after 30 years? (b) How many years will it be until an initial supply of 750 grams of Plutonium 238 has decayed to half of its initial mass?
Radon, one of the noble gases, is a decay product of uranium and is itself radioactive, with a half-life of 3.8 days3.8 days. As a heavy gas, radon can accumulate in low areas such as basements and crawl spaces. Consequently, radon is considered a significant source of air pollution and radiation exposure and, according to the EPA, is the second most frequent cause of lung cancer in the United States. Write the nuclear equation for the alpha decay of Rn‑222. nuclear equation:

(A) if both sentences are true, (B) if both sentences are false, (C) if the first sentence is true but the second is false, and (D) if the first sentence is false but the second is true. 1. Tap water is more pure than distilled water. The purity and cleanliness of distilled water remains constant no matter where you get it from, because of the process it has undergone. 2. Carbon dating is an application of nuclear chemistry where they use the amount of C-14 in a fossil to determine its age. Nuclear power plants produce radioactive wastes. 3. The density of water is dependent on its temperature. A water molecule has a linear structure because of the neutral charges of its atoms. 4. Sedimentation is a chemical water treatment process using gravity to remove suspended solids from water. Colloids are not likely to settle naturally because of Brownian motion and electrostatic forces balancing the gravity. 5. Uranium is mined. A uranium ore may directly be used as a fuel in a nuclear…
