In calculating the concentration of [cu(nh3)4]2+ from [cu(h2o)4]2+, the stepwise formation constants are as follows: k1=1.90×104 k2=3.90×103 k3=1.00×103 k4=1.50×102 calculate the overall formation constant (kf) for the formation of [cu(nh3)4]2+ from [cu(h2o)4]2+.

Kf = 1.11x10¹³

Explanation:

The value of Kf for a multistep process that involves an equilibrium at each step, is the multiplication of the constant of the equilibrium of each step.

Kf = K1xK2xK3xK4

Kf = 1.90x10⁴ x 3.90x10³ x 1.00x10³ x 1.50x10²

Kf = 1.11x10¹³

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
