Greater than
Explanation:
The dipole moment is the difference of electronegativity between the atoms in a molecule, and the total is the sum of the dipole moments of the bonds. So, it depends on the geometry of the molecule. When the dipole moment is 0 the molecule is nonpolar, when it is different from 0 the molecule is polar.
Both ClO₂ and SO₂ have angular geometry because there are lone pairs of electrons in the central atom (Cl and S), but Cl has a higher value of electronegativity than S, so the dipole moment must be greater.
SiF₄ is a nonpolar molecule, which has tetrahedral geometry and no lone pairs at the central atom. SF₄ has lone pairs at the central atom, and then the molecule is polar, so the dipole moment of SiF₄ is less than of SF₄.
The SO₃ molecule has no lone pairs at the central atom and has trigonal geometry, so it's a nonpolar molecule. SO₂ has angular geometry and it's a polar molecule, so the dipole moment of SO₂ is greater.
BeCl₂ has a linear geometry and is a nonpolar molecule. SCl₂ has an angular geometry, and it's a polar molecule, so the dipole moment of BeCl₂ is less than the dipole moment of SCl₂.
Oxygen has a higher electronegativity than the sulfur, and both molecules are polar with angular geometry, so the dipole moment of H₂O is greater.

Answer:
The answer to your question is 3 L of solution 40% and 2 L of solution 20%
Explanation:
Data
Final volume = Vf = 5000 ml = 5 L
Final concentration = Cf = 32%
Concentration 1 = C1 = 40%
Concentration 2 = C2 = 20%
Volume 1 = x
Volume 2 = 5 - x
Process
1.- Write an equation to solve this problem
VfCf = C1V1 + C2V2
2.- Substitution
32(5) = 40x + 20(5 - x)
3.- Solve for x
160 = 40x + 100 - 20x
160 - 100 = 40x - 20x
60 = 20x
60/20 = x
x = 3
Then, Volume 1 = 3 L
4.- Find Volume 2
Volume 2 = 5 - 3
Volume 2 = 2 L
