Calculate magnetic moment of a divalent ion in aqueous solution, if the electronic configuration is [Ar] 3d5 .

Ugo [173]

Answer:

5.47 B.M

Explanation:

✓We were given electronic configuration of argon as [Ar] 3d5.

✓This is a divalent ion. It has atomic number of 25.

✓magnetic moment can be calculated using below expresion

√[n(n+2)] .....................eqn(1)

✓ It has 5 unpaired electrons. Then n= 5

✓ [n(n+2)]

✓ substitute the ( n= 5) into eqn(1)

Then magnetic moment= [n(n+2)]

= [ 5(5+2) ]

= 5.47BM

against at -20 degree centigrade occupied the volume of one 40 ml calculate the temperature at which the volume of cash pickup 6

worty [1.4K]

The final temperature :T₂=411.125 K = 138.125 °C

<h3>Further explanation</h3>

Given

T₁=-20 °C+273 = 253 K

V₁=40 ml

V₂=65 ml

Required

Final temperature

Solution

Charles's Law

When the gas pressure is kept constant, the gas volume is proportional to the temperature

$\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}$

Input the value :

T₂=(V₂.T₁)/V₁

T₂=(65.253)/40

T₂=411.125 K = 138.125 °C
