The white color of Zn2+ complexes is attributed to the fact that Zn2+ lacks partially filled d orbitals for d-d electronic transitions that typically give rise to color in transition metal complexes. As a result, Zn2+ complexes do not absorb visible light in the range that produces color, leading to their white appearance.

What is the chemical formula for the ternary compound composed of Zn2 plus and OH ions?
The chemical formula for the ternary compound composed of Zn2+ and OH- ions is Zn(OH)2.
What are the spectator ions in Mg(s) plus Zn2 plus plus 2NO3- Mg2 plus plus 2NO3- plus Zn(s)?
The spectator ions are NO3- in this reaction. They are present on both sides of the equation before and after the reaction takes place, so they do not participate in the reaction and can be considered spectators.

How do quadratic equations relate to the Julia set fractal?
The Julia can be generated by a quadratic equation in the complex plane. Select a complex number c. Then for a point z in the plane, carry out the iteration, zn+1 = zn2 + c. Colour-code the point according to how many iterations are required before its magnitude exceeds any given threshold. Repeat for all z in the region of the plane.
