Solution and Explanation
(i) Heating causes a color change in \([Ti(H_2O)_6]^{3+}\) as electrons transition between energy levels.
(ii) A \(d^5\) ion with \(\Delta_0<P\) has the electronic configuration \(t_{2g}^4 e_g^2\).
(iii) \([Ni(CO)_4]\) exhibits \(sp^3\) hybridization and is diamagnetic because all electrons are paired.
