a)
![k _{sp} = [Ag {}^{ + } ][Cl {}^{ - } ] \\ but \: [Ag {}^{ + } ] = [Cl {}^{ - } ] \\ k _{sp} = [Ag {}^{ + } ] {}^{2} \\ [Ag {}^{ + } ] = \sqrt{k _{sp}} \\ = \sqrt{1.8 \times {10}^{ - 10} } \\ = 1.34 \times {10}^{ - 5} mol {dm}^{ - 3}](https://tex.z-dn.net/?f=k%20_%7Bsp%7D%20%3D%20%5BAg%20%7B%7D%5E%7B%20%2B%20%7D%20%5D%5BCl%20%7B%7D%5E%7B%20-%20%7D%20%5D%20%5C%5C%20but%20%5C%3A%20%5BAg%20%7B%7D%5E%7B%20%2B%20%7D%20%5D%20%3D%20%5BCl%20%7B%7D%5E%7B%20-%20%7D%20%5D%20%5C%5C%20k%20_%7Bsp%7D%20%3D%20%5BAg%20%7B%7D%5E%7B%20%2B%20%7D%20%5D%20%7B%7D%5E%7B2%7D%20%20%5C%5C%20%5BAg%20%7B%7D%5E%7B%20%2B%20%7D%20%5D%20%3D%20%20%5Csqrt%7Bk%20_%7Bsp%7D%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B1.8%20%5Ctimes%20%20%7B10%7D%5E%7B%20-%2010%7D%20%7D%20%20%5C%5C%20%20%3D%201.34%20%5Ctimes%20%20%7B10%7D%5E%7B%20-%205%7D%20mol%20%7Bdm%7D%5E%7B%20-%203%7D%20)
b)
It has not reached equilibrium because the silver concentration is not yet equal to the value of Ksp.
c)
Yes it will dissolve in order to establish the equilibrium.
Answer:
379.39K
Explanation:
We use the form of the general gas equation below:
P1V1/T1 = P2V2/T2
Given: p1 = standard pressure = 760mmHg= 760 torr. Torr is the same thing as mmmHg
P2 = 813 torr
T1 = standard temperature = 273k
T2 = ?
V1 = 22.4L
V2 = 29.1L
Rearranging the equation :
T2 = P2V2T1/P1V1
Substituting the values in the equation:
T2 = (813 * 29.1 * 273)/ (760 * 22.4)
T2 = 379.39K
After 30 years, about 4.7% of the americium atoms will have decayed to neptunium. Plutonium-239 is itself the primary fissile isotope of plutonium (used in nuclear weapons), and is in turn made from uranium.
