Write a net ionic equation for the reaction that occurs when excess nitric acid (aq) and copper(ii) carbonate are combined.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

the objects have the same charge is correct.
