Why does magma composition change during fractional crystallization? Different elements in the magma form crystals at different rates, leaving behind more of the unused elements. ... The crystals are denser than the magma.
No, education actually increased during the Renaissance. It was a time where people were discovering the philosophical nature of things, and were putting it into writing and such. The Renaissance was a time period where more and more people considered introspective ideas and more people studied topics such as art, science, mathematics, technology, music, and warfare.
Answer:
C. 7 is the pH scale of water.
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,
![[A_t]](https://tex.z-dn.net/?f=%5BA_t%5D)
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)
