[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)
Because the birds that fly overseas carry different flu viruses every year.
Answer:
0.366 moles to the nearest thousandth.
Explanation:
The molar mass of acetic acid CH3COOH = 2*12 + 4(1.008) + 2*16
= 60.03 g so the number of moles in 22 g
= 0.366.
Answer:
3 elements
Calcium,oxygen and hydrogen
