What else can I help you with?
A uranium235 sample starts with 200 atoms and 700 million years later there are 100 atoms What is the halflife of uranium235?
700 milliion years. The definition of half-life is the period of time during which one-half of the atoms of an element undergo decay into other elements.
What percentage do you have after 2 half lives?
After 2 half-lives, you would have 25% of the original amount remaining. Each half-life reduces the amount by half, so after two half-lives, you would have 25% left (50% reduced by half twice).
How much sample of 10g of tritium with half life of 12.32 after 2 half lives?
After 2 half-lives (two half-lives of tritium is 12.32 x 2 = 24.64 years), the initial 10g sample of tritium would have decayed by half to 5g.
How many half-lives have carbon gone through if 37245 years have passed and one half-life for carbon is 5730 years?
6.5 half-lives.
After three half lives what fraction of the daughter product has formed?
91.16% of the daughter product has formed after 3.5 half lives.
Decaying unstable element?
Uranium238

What is one bad use of uranium235?
can cause lung cancer
When was How the Other Half Lives created?
How the Other Half Lives was created in 1890.
How The Other Half Lives was created?
How the Other Half Lives was created in 1890.
What is true about the fission of uranium235?
The reaction produces more neutrons than were needed to start it.
How many half-lives have passed?
To determine how many half-lives have passed, you would need to divide the total time passed by the half-life of the substance. The result would give you the number of half-lives that have occurred.
What percentage do you have after 2 half lives?
After 2 half-lives, you would have 25% of the original amount remaining. Each half-life reduces the amount by half, so after two half-lives, you would have 25% left (50% reduced by half twice).
How much sample of 10g of tritium with half life of 12.32 after 2 half lives?
After 2 half-lives (two half-lives of tritium is 12.32 x 2 = 24.64 years), the initial 10g sample of tritium would have decayed by half to 5g.
How many half-lives have passed if 12.5 of a radioactive sample are left?
3 At the end of the first half life, there will theoretically be 50% remaining. 2 half lives: 25% 3 half lives:12.5 %
What was one cause for improvements in the slums?
Jacob Riis' book, How the Other Half Lives
What is the form of nuclear energy?
Nuclear energy as used in power plants results from fission of uranium235 and plutonium239
