HELLO! I NEED HELP. THANK YOU

1. Consider an octahedral complex ion with a central metal ion that has 7d-electrons, XB64XB64 has one unpaired electron in the ground state. a) Is the ligand, B2, a strong field ligand or a weak field ligand? Explain your answer and in your answer include the drawing the splitting energy diagrams.( 0.4pt) b) Is the complex ion high spin or low spin? Explain your answer. (0.4 pt) c) Is the pairing energy in the complex ion greater than or less than the splitting energy, oct.. Explain your reasoning. (0.4pt) d) Is the complex ion diamagnetic or paramagnetic? Explain your answer. (0.4 pt) 2. The octahedral crystal field splitting energy, oct, of Fe(ox)33 is 199kJ/mol. What is the color of a solution containing this complex ion? Show all calculations at each step and include units at each step in your calculations. ( 2.7pts ) Planck's constant =h=6.6261034Js/ photon Speed of Light =c=3.00108m/s
