Write the condensed ground-state electron configurations of these transition metal ions, and state which are paramagnetic:
Zinaida [17]

The electron configuration of  V³⁺ is [Ar]3d^2. The ion is paramagnetic because it has two unpaired electrons

<h3>What is paramagnetic?</h3>
  • A weak magnetic field supplied externally can weakly attract some materials, which then create internal magnetic fields that are directed in the same direction as the applied magnetic field. This phenomenon is known as paramagnetic.
  • Diamagnetic materials, in contrast, are attracted to magnetic fields and produce induced magnetic fields that are directed in the opposite direction from the applied magnetic field.
  • The majority of chemical elements and some compounds are considered to be paramagnetic materials.
  • Paramagnetic materials have a relative magnetic permeability that is somewhat more than 1, which makes them attracted to magnetic fields.
  • The applied field induces a linearly decreasing magnetic moment that is relatively weak.
  • Modern experiments on paramagnetic materials are frequently done with a sensitive analytical balance since it typically requires a sensitive analytical balance to identify the effect.

What is the value of the equilibrium constant K ?
lorasvet [3.4K]

Answer:

K = 0.0209

Explanation:

K = \frac{[H_{2}][I_{2}]}{[2HI]^{2}}

K = \frac{[4.35 x 10^{-2} ][2.79 x 10^{-2} ]}{[0.241]^{2} }

K = 0.0208958

K = 0.0209
