Well , I will say this is a false statement.
This is because compounds which were all made by the same bond have same physical properties but different chemical properties.
Chemical Properties :
How do the subtances react with ( water, acid,alkaline, base , gas like oxygen, etc. )
Physical Properties :
- Solubility of those subtances in (water or organic solvent )
- Electric Conductivity
- Melting or Boiling Point
- Density
- Smell (exp : Ammonia has pungent smell , Esters has fruity smell)
Answer:
The stronger the intermolecular forces are, the more energy is required, so the higher the melting point is. Many intermolecular forces depend on how strongly atoms in the molecule attract electrons — or their electronegativity.

hope you satisfied with my answer , if anything wrong in my answer , I May rewrite it !!!!
Answer: 55.56 moles of MgO
Explanation:
1 mole = avogadro number
if 6.21x10^25 atoms then molecules of MgO (equal numbers of Mg and O atoms)
= 0.5*6.21x10^25 = 3.105 molecules of MgO
So moles of MgO = 0.5*6.21*10^25/avogadro number = 55.56
My professor told me to use a 500ml beaker depending on what your mixing.
