Find the solubility of agi in 2.5 m nh3 [ksp of agi = 8.3 × 10−17; kf of ag(nh3)2+ = 1.7 × 107].
vovangra [49]
When the first reaction equation is:

AgI(S) ↔ Ag+(Aq)  +  I-(Aq)

So, the Ksp expression = [Ag+][I-]

∴Ksp = [Ag+][I-] = 8.3 x 10^-17

Then the second reaction equation is:

 Ag+(aq)  + 2NH3(aq) ↔  Ag(NH3)2+  

So, Kf expression = [Ag(NH3)2+] / [Ag+] [NH3]^2

∴Kf = [Ag(NH3)2+] /[Ag+] [NH3]^2 = 1.7 x 10^7

by combining the two equations and solve for Ag+:

and by using ICE table:

               AgI(aq) + 2NH3  ↔  Ag(NH3)2+  + I-
initial                        2.5                    0            0 

change                    -2X                    +X             +X

Equ                     (2.5-2X)                   X               X

so K = [Ag(NH3)2+] [I-] / [NH3]^2

Kf * Ksp = X^2 / (2.5-2X)

8.3 x 10^-17 * 1.7 x10^7 = X^2 / (2.5-2X) by solving for X

∴ X = 5.9 x 10^-5 

∴ the solubility of AgI = X = 5.9 x 10^-5 M

The equilibrium constant, Kc, for the reaction N2O4(g)⇌2NO2(g) is 5.0×10−3. If the equilibrium mixture contains [NO2] = 0.050 M
Sergeu [11.5K]

Answer:

0.50 M is the molar concentration of N_2O_4.

Explanation:

The equilibrium constant of the reaction = K_c=5.0\times 10^{-3}

N_2O_4(g)\rightleftharpoons 2NO_2(g)

Equilibrium concentration of NO_2 = 0.050 M

[NO_2]=0.050 M

Equilibrium concentration of N_2O_4 = ?

[N_2O_4]= x

The equilibrium constant of the reaction is given aSL:

K_c=\frac{[NO_2]^2}{[N_2O_4]}

K_c=\frac{(0.050 M)^2}{x}=5.0\times 10^{-3}

x = 0.50 M

0.50 M is the molar concentration of N_2O_4.

One agent of chemical weathering is _______________ which combines with water to form carbonic acid
ololo11 [35]
I believe the answer is carbon dioxide. Because when carbon dioxide and water combine in the atmosphere it forms a very weak acid called carbonic acid, which falls to the Earth's surface as precipitation.
