Calculate the rate constant for the beta decay of the carbon-14 isotope and calculate the half-life of the carbon-14 isotope. Given: 2,850 years for 71.0% of the carbon-14 isotope to decay. Show your calculations with the appropriate units.
Two carbon atoms present in the fossils are used to calculate the age of the fossils bones (and, in general, in all living material): carbon 12 and carbon 14. Both atoms behave similarly, but carbon 12 does not degrade over time, while carbon 14 does, as it is more unstable, but it does so slowly and steadily. Every 5730 years, half of carbon 14 is degraded, that is, the half-life of this atom. This carbon 14 measurement works well for estimating ages up to about 60,000 years, for longer times uranium 238, potassium 40 or rubidium 87 are used. The initial amount of carbon 14 can be estimated from carbon 12 or by knowing that carbon-14 transforms into nitrogen-14 over time, but the number of atoms totals stay the same. The equation that has been determined to describe radioactive decay, knowing the half-life, is given by N/N0 = 2(-t/t1/2), where N is the quantity of the radioactive substance at time t, with a half-life of t1/2 and an initial amount of N0. a) A rock contains 2 grams of…
Why do all living organisms contain a uniform amount of carbon-14? fill in the blank (carbon, oxygen, nitrogen) The continuous formation of -14 in the atmosphere and its continuous decay back to -14 produces a nearly constant equilibrium concentration of atmospheric -14. That -14 is oxidized to carbon dioxide and then incorporated into plants by photosynthesis. It is also incorporated into animals because animals ultimately depend on plants for food (they either eat plants or eat other animals that eat plants). Consequently, all living organisms contain a residual amount of -14.
A research group discovers a new version of happyase, which they call happyase*, that catalyzes the chemical reaction: HAPPY↽⇀SAD The researchers begin to characterize the enzyme. The researchers determined the kcat of the enzyme to be 555 s-1. In a separate experiment with [Et] at 3.2 nM and [HAPPY] at 55 µM, the researchers find that ?0 is equal to 220 nM s−1. What is the measured ?m of happyase* for its substrate HAPPY?
