1. Several students performed this experiment without paying adequate attention to the details of the procedure. Briefly explain what effect each of the following procedural hanges would have on the size of the volume- to- temperature ratio calculated by the students. (a) One student failed to replenish the boiling water in the boiling- water bath as the flask was being heated. At the end of the 6 min of heating, the boiling water in the bath was only in contact with the lower portion of the flask. (b) Following the proper heating of the flask in the boiling water, a student removed the flask from the boiling- water bath but only partially immersed the flask in the ice-water bath during the cooling period. (c) A student neglected to close the pinch clamp before removing the flask from the boiling water bath and immersing it in the ice-water bath. (d) One student neglected to measure the volume of the flask before leaving the laboratory. Because the procedure called for a 125-mL…

According to Wikipedia, Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. 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…
