An artifact contains 1/4 as much carbon-14 as the atmosphere. How old is the artifact

1 answer:

4 0

The artifact appears to have gone through 2 half-lives.
One half-life for Carbon-14 is 5730 years.
After 5730 years, there would be 1/2 as much carbon-14
After another 5730 years, there would be 1/4 as much carbon-14

The answer is roughly 11,460 years

Natalija [7]

The main formula is as follow is explained in the attached file (please look at the examples)

the 1,3- butadiene is h2c=ch-ch=ch2, so we have

sp² sp² sp² sp²
h2c = ch - ch = ch2

<span>the hybridization of the carbon atoms is </span>sp² : trigonal planar
