[GET ANSWER] Americium-241 is widely used insmoke detectors. Calculate theamount of americium-241 consumedin a smoke detector (initially containing5.00 g of Am) that has been used forone year if the half-life is 433 years.A) 4.99 gB) 0.00800 gC) 1.61 gD) 0.00160 gE) 3.39 g

SOLVED:Calculate how much of a 10.0-g sample of americium-241 remains after four half-lives. Americium-241 is a radioisotope commonly used in smoke detectors and has a half-life of 430 y.

Smoke detectors contain a small amount of americium-241. Its decay product is neptunium-237. Identify the emission from americium-241. | Numerade

SOLVED:Write a balanced nuclear equation for the alpha decay of americium-241.

Americium-241 is used in smoke detectors. It has a rate constant for radioactive decay of k=1.6 ×10^-3 yr^-1. By contrast, iodine- 125, which is used to test for thyroid functioning, has a rate constant for radioactive decay of k=0.011 day ^-1. (a) What are the half-lives of these two isotopes? (b) Which one decays at a faster rate? (c) How much of a 1.00-mg sample of either isotope remains after three half-lives? | Numerade
