Question

The hydrogen bonding between two nitrogen trihydride (NH3) molecules is an example of __________.

adhesion

cohesion

adhesion and cohesion

London dispersion

Answer 1

What do you think?

Answer 2

Do you know what each of those are, first of all?

Answer 3

@abb0t Not really which is why I asked.

Answer 4

\(\sf \color{red}{Cohesion}\) is the property of like molecules (of the same substance) to stick to each other due to mutual attraction
\(\sf \color{blue}{Adhesion}\) is a property of different molecules or surfaces to cling to each other
\(\sf \color{orange}{London ~dispersion}\) is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles

Answer 5

So adhesion?

Answer 6

One example, solids: they have high cohesive properties so they do not stick to the surfaces they come in contact. On the other hand, gases have weak cohesion. Water has both cohesive and adhesive properties. Water molecules stick to each other to form a sphere. This is the result of cohesive forces. When contained in a tube, the water molecules touching the surface of the container are at a higher level. This is due to the adhesive force between the water molecules and the molecules of the container.

Answer 7

Hydrogen bonding that occurs between two ammonia molecules. one between the lone pair of electrons on the nitrogen and one of the hydrogens on an adjacent ammonia molecule.
