[attention grabbing title here]

[deadskulz]

Suppose you start with 100 grams of the radioactive isotope Carbon-14, which has a half-life of 5,000 years. After 20,000 years, how much parent material will remain and how much daughter material will be produced?

answers plawks?
already looked in my bio book and i couldnt find it...

6.25 Grams of parent material left.

How? Half life of a radioactive material is x. Meaning, every x years the amount of radioactivity will have dropped by 50%. See where this is going? Find the daughter material yourself.

And mega tons = million tons. He is trolling, that would be 10,000,000,000 pounds. (10 billion.) Now how the fuck would that come out out of 100 grams?

The title diidnt catch my attention, but yet i clicked just to post this..

[[MPGH]Austin]

5 megatons.

[deadskulz]

5 megatons.

howd you need that?

its not required, but im thinking you trollin'.

[Swiftdude]

since when is this bio

[deadskulz]

since when is this bio

since there was radiometric dating :3

this is freshman bio lol.

its not required, but im thinking you trollin'.

because 5 megatons is the obvious answer.

im gonna fail my bio class when i take it next fall

fuck it, im writing that.

this is freshman bio lol.

Damn my high school freshmen classes are so behind
All I know is radioactive decay

[deadskulz]

im gonna fail my bio class when i take it next fall

your an 8th grader?

i dont even know what the is lol.

AHAHAHAHAHA


do it.

i only learned neutrons, electrons and protons in my high school at 11th grade in chemistry.

your an 8th grader?
o:

college freshmen

[Swiftdude]

didnt have radiometric dating in my bio class
