please help me with #4, 5, and 6. thank you!

please help me with this page, I need help with all of them. thank you!

4. Recopy the table shown on your paper or electronic device. Use a straight edge when drawing lines to make the table. (0.3pt) Write the formula for the complexes that form between the following metal ion centers and ligands and indicate the coordination numbers of the metal ion centers. You may use the appropriate abbreviations for the bidentate ligands in the formulas. 5. Write a reasonable formula of an octahedral complex ion that contains the following: - a transition metal ion that is not used in Questions 4&6,(0.5pt) - a single bidentate ligand ( 0.5pt) - two different monodentate ligands from the spectrochemical series shown above and one of these ligands must a charge. (You can choose how many of each ligand.) (0.5pt) - the complex ion has an overall negative charge. (0.5pt) (The complex ion does not have to exist but just be reasonable.) 6. The bidentate ligand, en =NH2CH2CH2NH2= Draw the structure of the following complex ions shown below. Draw all metal center ions and any bonds to the ligands. Draw all C,H,O and N atoms and include any lone pairs on the ligands. However, You may IGNORE any lone pair electrons on the metal ion centers. Remember that bidentate ligands make two single bonds to the metal center ion. You do not need to assign any formal charges on any atoms but give the overall charge of the complex ion. (0.8pts each) a) Ni(H2O)62+ b) Ni(NH3)62+ c) Ni(en)(H2O)42+ d) Ni(en)2(H2O)22+ e) Ni(en)32+
