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>

Calculate the molarity of a solution if there are 1.5 mol of NaCl in 2.3 L of solution
frosja888 [35]

Answer:

0.6522 mol/L.

Explanation:

<em>Molarity is defined as the no. of moles of a solute per 1.0 L of the solution.</em>

<em />

M = (no. of moles of solute)/(V of the solution (L)).

<em>∴ M = (no. of moles of solute)/(V of the solution (L)) </em>= (1.5 mol)/(2.3 L) = <em>0.6522 mol/L.</em>
