Answer:
Oxygen exists as a diatomic molecule in nature when it is not combined with any other element. It forms O2 molecule because it is stable when it is uncombined. ... By achieving octet configuration, the diatomic elements become more stable compared to the single atom. Therefore, oxygen and hydrogen are diatomic.
Explanation:
Hope it helps you..
Your welcome in advance..

Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. We can observe some physical properties, such as density and color, without changing the physical state of the matter observed<span>.</span>
Hello!
Reaction rate, the speed at which a chemical reaction proceeds.
Oh yes another person answered the same thing before me. Sorry if I was inconvenient.
Hope you pass or understand everything, though! Good luck!

Answer:
Because dipole - dipole force is stronger than london dispersion force
Explanation:
Intermolecular forces determines a wide range of physical properties of matter of which melting point is one of them.
Both london dispersion forces and dipole- dipole forces are vanderwaals force.
But diople - dipole forces exists between polar molecules which are molecules with permanent dipoles.
In london dispersion forces the dipole is temporary
