Radon is a colorless, odorless, radioactive noble gas. Because it occurs naturally in soil, it canbecome trapped in homes and buildings. Despite a short half-life of only 3.83 days, highconcentrations of radon indoors can pose a risk of lung cancer. (For this reason, many modernhomes and buildings have radon reduction systems installed.)Consider an enclosed space in a building which contains 3.03 g of radon gas at time t = 0.What mass of radon (in g) will remain in this space after 2.20 days have passed?|9Need Help?Read It

Solution: As per the given data,

Another series of nuclear reactions that can produce energy in the interior of stars is the cycle described below. This cycle is most efficient when the central temperature in a star is above 1.6 × 107 K. Because the temperature at the center of the Sun is only 1.5 × 107 K, the following cycle produces less than 10% of the Sun’s energy. (a) A high-energy proton is absorbed by 12 C. Another nucleus, A , is produced in the reaction, along with a gamma ray. Identify nucleus A decays through positron emission to form nucleus B. (c) Nucleus B absorbs a proton to produce nucleus C and a gamma ray. Identify nucleus C absorbs a proton to produce nucleus D and a gamma ray. Identify nucleus D. (e) Nucleus D decays through positron emission to produce nucleus E. Identify nucleus E. (f) Nucleus E absorbs a proton to produce nucleus F plus an alpha particle. What is nucleus F ? Note: If nucleus F is not 12C—that is, the nucleus you started with—you have made an error and should review the sequence…

An old campfire is uncovered during an archaeological dig. Its charcoal is found to contain less than 1/1000 the normal amount of 14C. Find the minimum age (in years) of the charcoal. Carbon-14 has a half-life of 5730 years which means half of it will be gone after 5730 years. You may find the equality 210 = 1024 to be useful.
