g If potassium cyanide is dissolved in water you can say that the equilibrium concentrations of potassium and cyanide ions are: ...fill in the blank 1 ...A. High ...B. Moderate ...C. Low

High

Explanation:

Concentration in chemistry refers to the amount of substance present in a system.

If potassium cyanide is dissolved in water, we have the following equilibrium being set up in solution;

KCN(aq) ⇄K^+(aq) + CN^-(aq)

This means that the concentration of both potassium ions and cyanide ions increases.

Hence, If potassium cyanide is dissolved in water you can say that the equilibrium concentrations of potassium and cyanide ions are high in the solution.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

increased stability in the completion of fluorine's outer shell.
