Answer:
Q < Ksp
Explanation:
The general equilibrium of a constant product solubility, ksp, is:
AB ⇄ A⁺ + B⁻
<em>Where Ksp is defined as:</em>
Ksp = [A⁺] [B⁻]
When [A⁺] [B⁻] = Ksp, the solution is saturated or oversaturated because there are the maximum amount of ions that solution can dissolve.
When the solution is oversaturated, AB is produced.
Now, in a unsaturated solution, the [A⁺] [B⁻] is less than the maximum amount that can be dissolved. That means:
[A⁺] [B⁻] = Q < Ksp
Q is defined in the same way than Ksp, just in Q the system is not in equilibrium.
Right answer is:
<h3>Q < Ksp</h3>
Because if all the trees and grasslands are to disappear and turn into deserts then there would be no oxygen for us
Answer:
The gas that Dr. Brightguy added was O₂
Explanation:
Ideal Gases Law to solve this:
P . V = n . R . T
Firstly, let's convert 736 Torr in atm
736 Torr is atmospheric pressure = 1 atm
20°C = 273 + 20 = 293 T°K
125 mL = 0.125L
0.125 L . 1 atm = n . 0.082 L.atm / mol.K . 293K
(0.125L .1atm) / (0.082 mol.K /L.atm . 293K) = n
5.20x10⁻³ mol = n
mass / mol = molar mass
0.1727 g / 5.20x10⁻³ mol = 33.2 g/m
This molar mass corresponds nearly to O₂
I got B. Because the answer is K2SO4, I got it right on my test so I know its right
