The answer is B) gain 8 electrons
Answer:it all above
Explanation:
it all above because all the answer are truth so it all above
Ln(800/3200) = - kt
t = 24 years.
ln(0.25) = -k*24
(- 1.3863) = -k*24
1.3863 / 24 = k
0.05776 = k
ln(0.5) = -k*t
-0.6931 = - 0.05776 t
12 = t
I don't know if you can just look at the question and know the answer. If 24 years is a quarter life then is it obvious that the 1/2 life is 12 years? It might be, but the method I've used works for sure.
Because it helps enriches the soil, just like when you make home made compost you add egg shells and old veggies and stuff all the vitamins enriches the compost.
Hope this helped.
