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

If you have 2 of the same substance and they are at the same temperature but have a different amount, what changes?
Lina20 [59]

Answer:

The heat energy stored within them changes

Explanation:

Heat energy is a function of the mass of a body, its specific heat capacity, and its temperature.

In this case, the bodies have the same specific heat capacity since they are made from the same material and the same temperature.

To get the quantity of heat stored in a body, we need to multiply all three parameters as shown below

Q = mC \Delta T

An increase in mass, through an increase in the amount of substance of a material present, will cause a corresponding increase in the heat energy stored within the material

The heat of vaporization for water is 40. 7 kJ/mol. How much heat energy must 150. 0 g of water absorb to boil away completely?
netineya [11]

The heat absorbed by the water sample for vaporization has been 6,105 kJ. Thus, option D is correct.

The heat of vaporization has been the amount of heat required to vaporize 1 gram of liquid.

The heat required for the vaporization has been given as:

Q=m\Delta H_{vap}

<h3 /><h3>Computation for the Heat of vaporization</h3>

The heat of vaporization of water has been given as, \Delta H_{vap}=40.7\;\rm kJ/mol

The mass of water sample has been, m=150\;\rm g

Substituting the values for the heat energy absorbed, <em>Q:</em>

<em />

<em />Q=150\;\times\;40.7\;\rm kJ\\&#10;\textit Q=6,105\;kJ

The heat absorbed by the water sample for vaporization has been 6,105 kJ. Thus, option D is correct.
