Answer:
[tex]\frac{1}{8}[/tex]
Explanation:
The half-life of carbon (5730 y) is the time it takes for half the carbon to decay.
After one half-life, half (50 %) of the original amount will remain.
After a second half-life, half of that amount (25 %) will remain, and so on.
[tex]\text{17 190 y} \times \frac {\text {1 half-life}}{\text{5730 y}} = \text{3 half-lives}[/tex]
We can construct a table.
No of half-lives Fraction remaining
1 [tex]\frac{1}{2}[/tex]
2 [tex]\frac{1}{4}[/tex]
3 [tex]\frac{1}{8}[/tex]
The general formula is
[tex]\text{Fraction remaining} = \frac{1}{2^{n}}[/tex]
where n = the number of half-lives.
Thus, [tex]\frac{1}{8}[/tex] of the original carbon remains after 17 190 y.
The study of chemicals and bonds is called chemistry.
The correct answer to the question is 1/8years.
What is half-life?
- Half-life is the time required for a quantity to reduce to half of its initial value.
According to the question, the solution is as follows:-
The half-life of carbon (5730 y) is the time it takes for half the carbon to decay. After one half-life, half (50 %) of the original amount will remain. After a second half-life, half of that amount (25 %) will remain, and so on.
The formula used to solve the question is as follows:-
[tex]17190Y*\frac{1}{5730}=3 half \ life[/tex]
The formula used to check the half-life:-
[tex]half \life =\frac{1}{2^n}[/tex]
- Where n is the half-life.
Thus the half-life 17190 is [tex]\frac{1}{8}[/tex].
Hence, the correct answer is 1/8.
