The ground-state electron configurations of
transition metal ions are diamagnetic [Kr]
. The ion is diamagnetic because there all electrons are paired.
<h3>
What is Diamagnetic?</h3>
- A magnetic field repels diamagnetic materials because it induces an opposing magnetic field in them when it is applied, which produces a repelling force.
- In contrast, a magnetic field draws paramagnetic and ferromagnetic materials together.
- All materials experience the quantum mechanical phenomenon known as diamagnetism, which is the only source of magnetism in a material.
- The magnetic dipoles within paramagnetic and ferromagnetic materials exert an attracting force that outweighs the modest diamagnetic force.
- Diamagnetic materials have a magnetic permeability that is less than vacuum, or 0.
- Although superconductors behave as strong diamagnets, diamagnetism is often a modest effect that can only be observed by sophisticated laboratory equipment.

Answer:
The volume of the flask is<u> 20.245 litres .</u>
Explanation:
We are given with following information-
-------- 1
where R =
Molar mass of 
The given chemical equation is -
--------- 2
Now , calculation -
Mass of
formed = 118g
Molar mass of
= 
Mole = 
Therefore , moles of
formed = 
From equation 2 , we get to know that ,
2mole
formed from 5 mole 
Therefore ,
mole
formed from
mole 
Moles of
used =
R= 
Pressure (P)= 1.85atm
Temperature (T)= 322K
Moles of
(n)=
moles
Applying the formula above in 1 equation , that is
PV = nRT
putting the given values -

V = 20.245 litres.
Hence , the volume of the flask is <u>20.245 litres . </u>
Answer: colloid
Explanation:
Colloids are solutions in which small sized particles are suspended throughout the solution as they do not settle own their own. Colloids are defined as the mixtures where the size of the particle is within the range of 2nm to 1000 nm. In these mixtures, physical boundary is seen between the dispersed phase and dispersed medium.
Colloids are solutions with particle size intermediate between true solutions and suspensions. Suspensions have large sized particles which settle when left undisturbed for sometime and thus can be filtered off easily. The particle size in colloids is less and hence they do not settle under the effect of gravity.
