ICl has a higher boiling point than Br2. What is the best explanation for this?
Burka [1]

Answer:

b. ICl experiences dipole-dipole interactions

Explanation:

The molecule with the <em>stronger intermolecular forces</em> will have the higher boiling point.

In Br₂, the Br-Br bond has a <em>dipole moment of zero</em>, because the two atoms are identical.

In ICl, the I-Cl bond, has two different atoms. One must be more electronegative than the other, so there will be a <em>non-zero bond dipole</em>.

ICl will have the higher boiling point.

a is <em>wrong</em>. Br₂ is nonpolar, so it has no dipole-dipole interactions.

c is <em>wrong</em>. Br₂ cannot form hydrogen bonds, because there is no hydrogen.

d is <em>wrong</em>. ICl has dipole-dipole interactions.

To three significant digit,what is the mass percentage of iron in the compound Fe2O3​
svlad2 [7]

69.9%

Explanation:

To find the mass percentage of iron in the compound in Fe₂O₃, we would go ahead to express the given molar mass of the iron to that of the compound.

 Mass percentage  = \frac{molar mass of Fe}{Molar mass of Fe_{2}O_{3}  }  x 100

Molar mass of Fe = 55.85g/mol

Molar mass of O = 16g/mol

Molar mass of Fe₂O₃ = 2(55.85) + 3(16) = 159.7‬g/mol

Mass percentage  = \frac{2(55.85)}{159.7}  x  100   = 69.94% = 69.9%
