Why isn’t there a lunar eclipse every time Earth is in between the sun and the Moon?

Chemistry
1 answer:
QveST [7]3 years ago
8 0

Answer: Exploratorium Senior Scientist Paul Doherty explains why not—the orbit of the moon is tilted relative to the orbit of the Earth around the sun, so the moon often passes below or above Earth. At those times, it does not cross the line between the sun and the Earth, and therefore does not create a solar eclipse.

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.
