The intermolecular forces that are responsible for the dissolution of Ethylene glycol in water is hydrogen bonding dipole-dipole forces and dispersion forces.
Both ethylene glycol and water contains the pair of hydrogen and oxygen.
The hydrogen of one atom create a bond with the oxygen of other atom this results in the formation of intra molecular hydrogen bonding.
The electron are non uniformly distributed over the molecule or the atom which results in the fluctuation of the electron density in the atom.
So it creates are dispersion forces which is present all over the molecule this forces helps to increase the strength of the bond formed between the ethylene glycol and water because they have large masses.
Both ethylene glycol and water are polar molecules because of being polar they form dipole and the dipole of both the molecules interact with each other in order to form bond between the atoms which eventually results in the formation dissolution of ethylene glycol in water.

Explanation:
Intermolecular force s between particles in a matter holds particles of molecules together in substances.
- The stronger the intermolecular forces the more solid a substance is.
- The weakest intermolecular attraction are found in gases as they have negligible attractive forces in between their particles.
- Solids are held together by very strong attractive forces.
- Liquids have weak forces holding them in place and this allows for a little movement.
- Gases are typically have very weak to negligible attractive forces.
One way to look at it is to determine whether the compound is acidic or basic. basic compounds will dissolve more easily in acid
A) Al(OH)3 is the hydroxide of a metal and this is basic. hence this will dissolve better in acid than pure water ( in fact Al(OH)3 is amphoteric meaning it can dissolve in both acid and base)
B) BaF2 is the salt of a strong base Ba(OH)2 and weak acid HF, hence the nature of BaF2 is slightly basic, this will dissolve better in acidic solution
C) PbCl2 is the salt of weak base Pb(OH)2 and strong acid HCl, hence the nature of PbCl2 is slightly acidic, it won’t be more soluble in acidic solution
D) Hg2Br2 is the salt of weak base Hg2(OH)2 and strong acid HBr. the nature of Hg2Br2 is acidic hence, it wont dissolve better in acidic solution
E) NiS is the salt of a very weak base Ni(OH)2 hence this NiS will be acidic in nature nd wont dissolve in acidic solution
F) AgI is the salt of a very strong acid HI and weak base AgOH. nature will be acidic and wont dissolve in acidic solution
in conclusion only Al(OH)3 and BaF2 are more soluble in acidic solution than in pure water as both are slightly basic
Answer:
Explanation:
Given that,
Mass, m = 456 mg = 0.456 g
Volume, V = 62 L
Since, 1 L = 1000 cm³
62 L = 62000 cm³
Using formula, density = mass/volume
So,
So, the density of an object is
