Bone age : 22,920 years
<h3>Further explanation</h3>
Given
Nt = 2.5 g C-14
No = 40 g
half-life = 5730 years
Required
time of decay
Solution
General formulas used in decay:
t = duration of decay
t 1/2 = half-life
N₀ = the number of initial radioactive atoms
Nt = the number of radioactive atoms left after decaying during T time
Input the value :
the answer is hydrocarbons contain 10 hydrogen atoms :D
The correct number of sig figs for this number is 7 because all whole numbers count and all zeros after the decimal counts too. So, all the numbers count, which is 7.
Answer:
1) B and 2) D
Explanation:
when scientists refer to the naked eye, it is referring to the eye without any sort of magnifying device, such as a microscope. Algae blooms can result naturally or by human interference
When the atoms of radioactive elements have an unstable nucleus. As the nucleus tries to become stable, it releases energy (ionizing radiation), and extra protons or neutrons in the form of alpha or beta particles.
