We can calculate years by using the half-life equation. It is expressed as:
A = Ao e^-kt
<span>where A is the amount left at t years, Ao is the initial concentration, and k is a constant.
</span>From the half-life data, we can calculate for k.
1/2(Ao) = Ao e^-k(1620)
<span>k = 4.28 x 10^-4
</span>
0.125 = 1 e^-<span>4.28 x 10^-4 (</span>t)
t = 4259 years
Answer: 6 & 8
Explanation:
I got it correct on my test hope this helped
B. a nucleus with a positive charge.
Answer:
Covalent bond
Explanation:
they will make a covalent bond with each other because both are non- metals and have a low electronegativity difference.
