The radioisotope 14C (half life = 5730 years) is used for carbon dating. What is the first order rate constant for ¹4C?

Hi, I need help with this step-by-step, please. Thank you.    Even more interesting is how the researchers determined the age of the sharks. Normally, youcould look at the decay of carbon-14 in the bone of an animal to determine its age. By comparingthe current amount of carbon-14 in the bone to the amount of carbon-14 that was in the boneinitially, you can determine how much time has passed (the age of the animal). This doesn’twork with Greenland sharks, though! Greenland sharks don’t have bones. They just havecartilage. Researchers determined, however, that the carbon-14 in certain proteins in the eye lensof the sharks could be dated because those proteins are set from the time that the shark is bornand are never replaced (most proteins in living organisms are constantly being broken down andreplaced, but not these proteins in the eye lens of the Greenland shark!).[Here’s the problem to solve and the information you need to solve it.] Let’s assume thatresearchers find a new Greenland…

question 1

The rate constant for the decay of a radioactive element is 2.09 x 10 3 day1. What is the half-life of this element? days 1 4 6. 8 9. +/- x 100 12:01 AM Type here to search 4/17/2021 3. 7. 近

A certain drug has a half-life in the body of 7.5 h. What should the interval betwe 60.% of its initial concentration? Round your answer to 2 significant digits.

Radioactive Decay is a first order process. In 1911 , maria curie prepared a n international radioactivity standard that conatined 22.00 mg of 226 Ra, which has a half life of 1620 years. How much Ra remained in 1977?

please answer all as they are part of 1 question but different questions,,.

radioactive Cs-131 is used to treat tumors by implementation directly in the tumor site. The radioactive decay of Cs-131 is first order with t1/2=9.7 days. If the tumor is implanted with Cs-131, how long will it take for 33% of the Cs-131 to be left in the tumor?
