When a plant or an animal dies, its 14C content decreases with a half-life 5730 years. If an archeologist finds an ancient firepit containing partially consumed firewood and the 14C content of the wood is only 15% that of an equal carbon sample from a present-day tree, what is the age of the ancient site?

Question 2 : The reaction A(aq) ---> B(aq) + C(aq) is a first order reaction. The half-life of A(aq) is 87.1 s at 25.0°C and its half-life is 65.8 s at 45.0°C. What is its half-life (in s) at 65.0°C? Question 3 : The half-life of 14C is 5730 years. A sample contains 90.9 % of the 14C that it would contain if it were still part of a living being. What is the age (in years) of this sample?

Question 7 1 pts The AC activity of an artifact from a burial site was 8.7/min.g C. The half-life of C is 5730 years, and the current activity is 16.1/min.g C (that is, 16.1 disintegrations per minute per gram of carbon). How old in years) is the artifact? Enter number to 1 decimal place. Question 8 1 pts Analysis of an ant found in a piece of amber provided 10 disintegrations of 14C/min.g C, whereas...

Question 1 : The reaction A(aq) ---> B(aq) is a first order reaction with respect to A(aq). The concentration of A(aq) is reduced to 33.1 % of its initial value in 1.54 minutes. What is this reaction's half-life (in s)? Question 2 : The reaction A(aq) ---> B(aq) + C(aq) is a first order reaction. The half-life of A(aq) is 91.0 s at 25.0oC and its half-life is 69.2 s at 45.0oC. What is its half-life (in s) at 65.0oC? ...

Carbon 14 is a radioactive isotope produced in the upper atmosphere by cosmic rays. It has a half-life measured as 5730 : 40 years. Since plants and animals absorb carbon from the atmosphere, the percentage of carbon a living organism contains that is carbon 14 is equal to the percentage of carbon 14 in the atmosphere. When an organism dies, however (or when a layer of wood is laid down as bark in a tree), it ceases to absorb carbon....
