Mesoscopic scale is roughly:

• below 10 nm

• below 1 nm

• above 1 micron

• above 1 micron

• from a few Angstroms to a few hundred nanometers

Choose repulsive interactions:

• van de Waals

• steric

• electrostatic between particles of different nature

• electrostatic between particles of the same nature

Choose short-range interactions

• steric

• hydrogen bonding

• van der Waals

• electrostatic between two point charges

Van der Waals forces cannot appear between polar molecules

• True

• Not true

Lennard-Jones potential takes into account:

• the van der Waals forces and electrostatic interactions

• the van der Waals forces and steric repulsion

• the van der Waals forces and hydrogen bonding

The larger the salt concentration, the longer the screening length (the Debye-Hückel length)

• True

• Not true
