[Co(CN)₆]³⁻ → Yellow
[Co(NH₃)₆]³⁺ → Orange
[CoF₆]³⁻ → Blue
Explanation:
- All the given compounds have octahedral geometry but the ligand in each are different with the same metal ion.
- Ligands strength order: CN⁻ > NH₃ > F⁻
- The ligand CN will act as a strong field ligand so that the splitting is maximum when compared to NH₃ and F⁻
- If the splitting is more, the energy required for transition is more, and the wavelength is inversely proportional to energy.
- So CN complex will absorb at lower wavelength (yellow color)
Answer:
<h2>Pressure will increase</h2>
Explanation:
At a constant temperature, the pressure of gas will increase proportional to the decrease in volume of the gas.
P1V1= P2V2
Decrease in volume result in increase in pressure as the equation has to hold true.

Answer:
Coal
Explanation:
Once it's all been mined, there's no more. It's not like we grow it.
