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

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
