Would you expect the Mg3[Cr(CN)6]2 to be diamagnetic or paramagnetic? Explain your reasoning.
bixtya [17]

Answer:

paramagnetic

Explanation:

The complex ion is : [Cr(CN)₆]³⁻

Oxidation state of Cr in [Cr(CN)₆]³⁻ is:

x + (-1)6 = -3

x = +3

CN⁻ is a strong field ligand which can result in  pairing of the electrons.

The electronic configuration of Cr is:

1s²2s²2p⁶3s²3p⁶3d⁵4s¹

The electronic configuration of Cr³⁺ is:

1s²2s²2p⁶3s²3p⁶3d³

<u>These 3 electrons will be singly present in the 3 degenerate t₂g orbitals and per Hund's rule, pairing will not occur in the same level energy orbitals. So , no. of unpaired electrons will be 3 and the complex will be paramagnetic.</u>

Gravity on Earth is 9.8 m/s2, and gravity on the Moon is 1.6 m/s2.
Ivanshal [37]

Answer:

Mass is the same but it weights 64 Newtons

Explanation:

First of Mass is the same in any sort of gravity. Now let's calculate weight

W = MG

where W = Weight

M = Mass

G = Gravity

W = (40kg)(1.6)

W = 64

Sorry for the spelling mistakes, hope this helps
