exactly 22.0 grams
because freezing is a physical change not a chemicl change..so nothing is taken away or added
Al2Se3 is your chemical formula
Hope this helps

Answer:
9.4
Explanation:
The equation for the reaction can be represented as:
+ ⇄
The ICE table can be represented as:
+ ⇄
Initial 0.27 0.49 0.0
Change -x -2x x
Equilibrium 0.27 - x 0.49 -2x x
We can now say that the concentration of at equilibrium is x;
Let's not forget that at equilibrium = 0.11 M
So:
x = [] = 0.11 M
[] = 0.27 - x
[] = 0.27 - 0.11
[] = 0.16 M
[] = (0.49 - 2x)
[] = (0.49 - 2(0.11))
[] = 0.49 - 0.22
[] = 0.27 M
= 9.4
∴ The equilibrium constant at that temperature = 9.4
