Based on the passage, one way in which the situation in the late 19th century affected the vision of Africa's future is by shattering it.
<h3>What does the excerpt state?</h3>
The except in the third paragraph talks about a vision of the future of Africa where the British control the entire continent.
This vision was shattered by the Scramble for Africa in the late 19th century that saw other European powers gaining colonies in Africa which meant that the British would never control the entire continent.

Explanation: ok will do no worries
From the calculations carried out , we can see that the molar solubility of Al(OH)3 is 8.6 x 10^-12 M
<h3>What is solubility?</h3>
The term solubility refers to the amount of substance that dissolves in a solution measured in moles per liter.
From the question we have initial [Al+3] = 0.05 M
Setting up an ICE table:
Al(OH)3(s) → Al3+ + 3OH-
I 0.05 0
C +x +3x
E 0.05+x 3x
Know that;
Ksp = [Al3+] [OH-]^3
Ksp = 1.3 x 10^-33
So;
[Al3+] = (0.05+X) and [OH-]^3 = 3X
If x = molar solubility of Al(OH)3
Then:
1.3 x 10^-33 = (0.05 + X) (3X)^3 by solving for X
x = 8.6 X 10^-12 M
