According to small molecules and ions, we order the intermolecular forces according to their relative strengths:
- Ion-Ion forces
- Ion-Dipole forces
- Hydrogen bonding
- Dipole-Dipole forces
- London's dispersion forces
This order is correct because of the nature of the different forces.
<h3>What is the nature of the various forces mentioned above?</h3>
- Ion-ion forces are the strongest because they involve the electrostatic attraction between two ions that have opposite charges.
- Ion-dipole forces involve the attraction between a charged ion and a polar molecule, which is weaker than the ion-ion forces.
- Hydrogen bonding is a particularly strong form of dipole-dipole interaction that is stronger than regular dipole-dipole forces.
- Lastly, London dispersion forces are the weakest of the forces because they are caused by temporary dipoles that form due to the random motion of electrons within a molecule.
For small molecules and ions, arrange the intermolecular forces according to their relative strengths.
List them from stronger to weaker:
- Ion-ion forces
- Hydrogen bonds
- Dipole-dipole forces
- Ion-dipole forces
- London dispersion forces

#SPJ4
Answer: Percent ammonia in is 38.2 % in 3 significant figures.
Explanation:
To calculate the mass percent of element in a given compound, we use the formula:
Molar mass of = 267 g/mol
Mass of =
Thus
Thus percent ammonia in is 38.2 % in 3 significant figures.
Answer:
Option B
Explanation:
As Brønsted-Lowry theory states, acids are the ones that can donate protons.
When a proton is donated, it is released to become medium more acidic.
HCl is a strong acid.
HCl (l) + H₂O (l) → H₃O⁺ (aq) + Cl⁻(aq)
These always reffers to strong acid where the dissociation is 100% completed.
In a weak acid, dissociation is not 100% complete, that's why we have an equilibrium.
HA (l) + H₂O (l) ⇄ H₃O⁺ (aq) + A⁻(aq) Ka
Calculating the number of mole of COSO4 reacted
=mass/R.F.M
R.F.M of CUSO4 is 63.54+32+64=159.6
moles is therefore 200g/159.54=1.254moles
since reacting ratio is 1:1 ,moles of Cu is also 1.254moles
mass is therefore moles x R.F.M
1.254x63.54=79.6g(answer C)
