Answer:
Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water.
Explanation:
The reaction is:
Cr₃⁺ +3 C₁₀H₈N₂ → [Cr(C₁₀H₈N₂)₃]³⁺
2,2\'-bipyridine is bidentate ligand and neutral. It exhibits two N terminal, thus, it functions as bidentate ligand.
Therefore, three 2,2\'-bipyridine ligand fulfills the six coordination number of Cr₃⁺.
The formula for the complex is [Cr(C₁₀H₈N₂)₃]³⁺
