If they're different sizes and densities, you are able to separate the substances.
I think it would be solubility but I’m not sure
Answer:
phone, microwave, internet box
Answer:
D) 0.86 M
Explanation:
Given that:
The rate constant, k = 6.7×10⁻⁴ s⁻¹
Initial concentration [A₀] = 1.33 M
Time = 644 s
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,
is the concentration at time t
So,
![[A_t]=1.33\times e^{-6.7\times 10^{-4}\times 644}](https://tex.z-dn.net/?f=%5BA_t%5D%3D1.33%5Ctimes%20e%5E%7B-6.7%5Ctimes%2010%5E%7B-4%7D%5Ctimes%20644%7D)
![[A_t]=0.86 M](https://tex.z-dn.net/?f=%5BA_t%5D%3D0.86%20M)
