The newly modified electrode was used for the determination of HQ in samples of various skin whitening creams . Three commercial skin bleaching creams were analyzed for their hydroquinone contents . The results for all cream samples with 2% and 4% HQ on the label are listed in Table 3 . The obtained recovery results indicate that AC−CPE modified electrode can be successfully used for the determination of the hydroquinone concentration in the skin whitening cosmetics samples .
Archaeologists have long used carbon -14 dating (also known as radiocarbon dating ) to estimate the age of certain objects . Traditional radiocarbon dating is applied to organic remains between 500 and 50,000 years old and exploits the fact that trace amounts of radioactive carbon are found in the natural environment . Now, new applications for the technique are emerging in forensics, thanks to . . .

There are also some tests that have been done that don't quite match up . For instance, bones of a sabre-toothed tiger, theorized to be between 100,000 and one million years old, gave a Carbon date of 28,000 years . A freshly killed seal, dated using Carbon -14, showed it had died 1300 years ago .

Carbon dating is based upon the decay of 14 C, a radioactive isotope of carbon with a relatively long half-life (5700 years) . While 12 C is the most abundant carbon isotope, there is a close to constant ratio of 12 C to 14 C in the environment, and hence in the molecules, cells, and tissues of living organisms .

Knowing that the half-life of carbon -14 is 5,730 years, it is easy to construct a decay curve like the one for M&Ms . Complete the following table and make a line graph of the data on the chart provided . The result should be a smooth, curving line through all points . Carbon dating is generally useful for dating objects up to about 50,000 years old .
The other major factor affecting the results of carbon dating is gauging the original proportion of carbon -14 itself . Carbon dating is based on the loss of carbon -14, so, even if the present amount in a specimen can be detected accurately, we must still know how much carbon -14 the organism started with . Scientists must assume how much carbon -14 was in the organism when it died .
Carbon dating is one of the archaeology's mainstream methods for dating organic objects up to 50,000 years old . This method is based on the idea of radiative decay of Carbon -14 isotopes over thousands of years . Through physics, scientists have discovered that radioactive molecules decay at a specific rate dependent on the atomic number and mass of . . .

The result was sample B at 16,120 years . The Allosaurus dinosaur was supposed to be around 140,000,000 years . The samples of bone were blind samples ." This test was done on August 10, 1990 Comment from a reader: " Of course carbon dating isn't going to work on your Allosaurus bone . That method is only accurate to 40,000 years .
A few examples of wild dates by radiometric dating : Shells from living snails were carbon dated as being 27,000 years old . 3; Living mollusk shells were dated up to 2,300 years old . 4; A freshly killed seal was carbon dated as having died 1,300 years ago . 5 "One part of the Vollosovitch mammoth carbon dated at 29,500 years and another part at 44,000 ." 6
The Kongsfjorden fjord in Norway . Scientists have for over half a century .relied on carbon dating to gauge the age of organic matter and help determine when some events happened .
