Answer : The maximum amount of nickel(II) cyanide is 
Explanation :
The solubility equilibrium reaction will be:
Initial conc. 0.220 0
At eqm. (0.220+s) 2s
The expression for solubility constant for this reaction will be,
![K_{sp}=[Ni^{2+}][CN^-]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BNi%5E%7B2%2B%7D%5D%5BCN%5E-%5D%5E2)
Now put all the given values in this expression, we get:
Therefore, the maximum amount of nickel(II) cyanide is
I am pretty sure u have pictures and this one should be the one that erika should make

A, Compression
Compression of a gas always requires work
The force exerted on the Kite is 49.6 N.
<u>Explanation:</u>
Force is nothing but the product of pressure exerted by the wind on the kite and the area of the kite.
F = P × A
Where,
F is the Force in Newton = ?
P is the Pressure = 113 Pa = 113 N/m²
A is the Area of the Kite
A = 0.836 m × 0.525 m = 0.4389 m²
Now, we can find the force as,
F = 113 N/m² × 0.4389 m²
= 49.6 N [ ∵ In the units, m² gets cancelled]
So the force exerted on the Kite is 49.6 N.
