Answer:
neutral atoms when an atom is charge less
Explanation:
Property of a fluid by which molecules of different kinds of fluids are attracted to each other is called adhesion.
Adhesion is the tendency of molecules of different kinds of fluids to cling to one another.
The forces responsable for the adhesion are the intermolecular forces.
One of the intermolecular forces is the London dispersion force. It is a temporary attractive force between molecules.
There are three types of adhesion: chemical adhesion, dispersive adhesion, and diffusive adhesion.
Cohesion is similar to adhesion, but it refers to identical or similar kinds of fluids to cling to one another.

Answer:
155 kJ
Explanation:
The energy change will be the energy of the reactants less the energy of the products. And the energy of each compound is the sum of the energy of their bonds. Let's call y the N-Br strength.
3HOBR = 3x(459 + 201) = 1980 kJ
NH₃ = 3x386 = 1158 kJ
3H₂O = 3x(2x459) = 2754 kJ
NBr₃ = 3y
3y + 2754 - 1158 - 1980 = 81
3y -384 = 81
3y = 465
y = 155 kJ
