[CO(en)₃]³⁺ is more stable than [CO(CH₃NH₂)]³⁺ to make more stable complex because of chelate effect.
[CO(en)₃]³⁺ is a metal chelate due to presece of bidentate ligand ethylene diamine ligand. Metal chelates are more stable than complexes containing only monodentate ligands because of the chelate effect, we expect ethylenediamine to form a stronger complex with Co than ammonia.
The Chelate Effect is that complexes resulting from coordination with the chelating ligand is much more thermodynamically stable than complexes with non-chelating ligands.
The chelate effect defined as the augmented affinity of chelating ligands for any metalic ion in comparison of the affinity of a similar nonchelating ligands for the same metallic ion.

They act together to neutralise each other. this reaction realeases carbon dioxide and the baking soda freezes in the ice.
Lead lV Sulfide or you could say Plumbic Sulfide, it's the same.
Answer:
The Following are the matching to this question:

Explanation:
- It includes creating assumptions, extracting predictions through logical outcomes, and experimentation observation based on those projections.
- Every information gathered only with sense is also an observation. It expresses concern relating to scientific research. It also helps research scientists gather data.
- Its independent variable inside an analysis is a controlled variable. It's also called "manipulated," because it can change its parameter, which is controlled one.
- The suggested explanation for an occurrence is a hypothesis. It belongs to the scientific method. That's an experimental forecast, which is checked.
- The experiment manipulates the important variables, calculates the dependent variable, controls any alien variables.
- It "reacts" to improvements inside an experiment that they make. It is the result or consequence of an experiment.
