Answer:
I think that temperature will be cut in half.
When volume increases, pressure decreases. As pressure decreases, temperature decreases. So if you double volume, pressure is halved and so will the temperature. I'm new to this, but I think that's the answer . Tell me if I'm right good luck!
NO, it should not be the process is still the same . the only factors about it that should change is the experiment itself.:)

8.34 moles
Explanation:
We are given 8.34 moles.
We need to find moles: 8.34
<h3>
Answer:</h3>
1.380 × 10^-8 M
<h3>
Explanation:</h3>
The pH is the measure of alkalinity or acidity of a substance.
It is the negative logarithm of H+ ions concentration [H+].
pH = -log[H+]
pOH on the other hand is negative logarith of OH- concentration [OH-].
pOH = -log[OH-]
In this case;
pOH = 7.86
We can calculate the [OH-]
pOH = -log[OH-]
But, pOH = 7.86
pOH = -log[OH-]
-log[OH-] = 7.86
[OH-] = Antilog -7.86
= 1.380 × 10^-8 M
Therefore, [OH-] is 1.380 × 10^-8 M
