Answer:
68,2%
Explanation:
Supposing the initial salt concentration of lake Parsons is the same of non-isolated lakes, 6,67L, and the change of salt concentration in isolated lake is just for water evaporation it is possible to write:
6,67gL⁻¹×X = 21gL⁻¹×Y
<em>-Where X is the initial water and Y is the water that remains in the isolated lake-</em>
Thus:
6,67X = 21Y
0,318 = Y/X
0,318 is the ratio of water that remains between total water. To obtain the ratio of evaporated water:
1-0,318 = 0,682
In percentage: <em>68,2%</em>

Answer: The value of the equilibrium constant Kc for this reaction is 0.088
Explanation:
where,
x = given mass
M = molar mass
= volume of solution in L
Equilibrium concentration of 
= 
Equilibrium concentration of 
= 
Equilibrium concentration of 
= 
The given balanced equilibrium reaction is,
The expression for equilibrium constant for this reaction will be,
![K_c=\frac{[CaO]\times [CO_2]}{[CaCO_3]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BCaO%5D%5Ctimes%20%5BCO_2%5D%7D%7B%5BCaCO_3%5D%7D)
Now put all the given values in this expression, we get :
