Answer:
5.65mg of the isotope remains
Explanation:
The radioactive decay follows the equation:
Ln[A] = -kt + ln[A]₀
<em>Where [A] is amount of the isotope after time t, k is decay constant, and [A]₀ is initial amount of the isotope.</em>
k = ln 2 / Half-life
k = ln 2 / 3.82 days
k = 0.18145days⁻¹
Replacing:
Ln[A] = -0.18145days⁻¹*10.1days + ln[35.3mg]
ln[A] = 1.7312
[A] = 5.65mg of the isotope remains

The central atom is carbon with three hydrogen and one chlorine atom around it. There are no unshared electrons on the carbon so it is tetrahedral.
It’s Benzene, I do believe :) hope this helped, good luck!

Octet-A group of 8 things or people
Answer:
When an organism dies or a leaf falls, it sinks into the earth's layers and decomposes. A carbon film is made when the oxygen, hydrogen and nitrogen of the organism disappear, leaving a thin layer of carbon. This process is known as distillation or carbonization.
Hope it helps!
