Let's solve the question step by step.

### Part I: Writing the Formulas for Coordination Compounds

#### (a) Tetraamineaquachlorido cobalt (III) chloride
1. Identify the ligands: Tetraamine (4 NH3), Aqua (H2O), and Chlorido (Cl).
2. The central metal is cobalt (Co) with an oxidation state of +3.
3. The formula is constructed as follows:
