The method was developed in the late 1940s at the University of Chicago by Willard Libby, who received the Nobel Prize in Chemistry for his work in 1960. It is based on the fact that carbon- 14 is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting carbon-14 combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire carbon-14 by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of carbon-14 it contains begins to decrease as the carbon-14 undergoes radioactive decay. Measuring the amount of carbon-14 in a sample from a…s.com/course.html?courseld%3D15828855&HeplD353706194671Of71a192e43597b01c6e0#10301 Principles of Chemistry I (Chem 1107-327) signments <09 - Pre-Lab 9.11 Pre-Lab Methane burns in oxygen to produce CO2 and H2O.
