Consider the insoluble compound nickel(II) hydroxide , Ni(OH)2 . The nickel ion also forms a complex with cyanide ions . Write a
natali 33 [55]

Answer: Equilibrium constant for this reaction is 2.8 \times 10^{15}.

Explanation:

Chemical reaction equation for the formation of nickel cyanide complex is as follows.

Ni(OH)_{2}(s) + 4CN^{-}(aq) \rightleftharpoons [Ni(CN)_{4}^{2-}](aq) + 2OH^{-}(aq)

We know that,

      K = K_{f} \times K_{sp}

We are given that, K_{f} = 1.0 \times 10^{31}

and,    K_{sp} = 2.8 \times 10^{-16}

Hence, we will calculate the value of K as follows.

     K = K_{f} \times K_{sp}

     K = (1.0 \times 10^{31}) \times (2.8 \times 10^{-16})

        = 2.8 \times 10^{15}

Thus, we can conclude that equilibrium constant for this reaction is 2.8 \times 10^{15}.

Alexeev081 [22]
Answer is: <span>Double Displacement.
Combustion is reaction with oxygen.
</span>Synthesis is reaction of two or more substances combining to make a more complex substance. 
Decomposition is reaction where one substance is broken down into two or more simpler substances. 
Single Displacement is reaction where  neutral element metal or nonmetal become an ion as it replaces another ion in a compound. 
<span>Double displacement reactions (more reactive metals displace metals with lower reactivity).
</span>Neutralization<span>is is </span>reaction<span> in which an </span>acid<span> and a </span>base<span> react quantitatively with each other.</span>
