Answer:
0.0185 min⁻¹
Explanation:
Using integrated rate law for first order kinetics as:
![[A_t]=[A_0]e^{-kt}](https://tex.z-dn.net/?f=%5BA_t%5D%3D%5BA_0%5De%5E%7B-kt%7D)
Where,
![[A_t]](https://tex.z-dn.net/?f=%5BA_t%5D)
is the concentration at time t
![[A_0]](https://tex.z-dn.net/?f=%5BA_0%5D)
is the initial concentration
Given:
20.0 % of the initial values is left which means that 0.20 of is left. So,
![\frac {[A_t]}{[A_0]}](https://tex.z-dn.net/?f=%5Cfrac%20%7B%5BA_t%5D%7D%7B%5BA_0%5D%7D)
= 0.20
t = 87.0 min
![\frac {[A_t]}{[A_0]}=e^{-k\times t}](https://tex.z-dn.net/?f=%5Cfrac%20%7B%5BA_t%5D%7D%7B%5BA_0%5D%7D%3De%5E%7B-k%5Ctimes%20t%7D)
<u>k = 0.0185 min⁻¹</u>
Answer:
dont get it wet or it wont work at all
Sodium. It reacts with most of every other element.
Answer:
Explanation: The answer is B. Because meiosis process produce genetically different, haploid cells. Also, meiosis basically happen to produce gametes. Gametes is haploid. So, the answer is B
