Midterm Reviewer Flashcards
Attractive forces that act between molecules
Intermolecular force (IMF)
It is an attraction between charges
Electrostatic force
It is called the positive charge
Protons
It is called the negative charge
Electrons
Are the charges particles
Ions
The weakest intermolecular force, attraction between nonpolar molecules
London Dispersion force
Stronger than london dispersion force, attraction forces between polar molecules
Dipole-dipole force
Attraction forces between polar and nonpolar molecules
Dipole-induced dipole
Attraction forces between single element and molecules
Ion-dipole force
What are the attractive forces of H-bonding?
Nitrogen, Oxygen, Fluorine
The strongest intermolecular force.
H-bonding
It has positive and negative charge in the end poles
Dipole
An attraction forces between nonpolar molecule and single atom
Ion-induced Dipole
It is an attraction between charges.
Electrostatic force
It is the measure of the elastic force in the surface of a liquid
Surface tension
It is the tendency of a liquid to rise in a narrow tube or to be drawn into small openings.
Capillary action
It is the measure of a fluid’s resistance to flow.
Viscosity
The greater the viscosity, the _________ the liquid flows.
slower
The lower the viscosity, the _________ the liquid flows.
higher
It is the Intermolecular attraction between like molecules.
Cohesion
It is the intermolecular attraction between unlike molecules.
Adhesion
Two types of viscosity.
High viscosity & Low viscosity
The equilibrium pressure of a vapor above its liquid, exerted by the vapor above the surface of the liquid in a closed container
Vapor pressure
It is the temperature which a liquid boils and coverts into a gas.
Boiling point
What is the normal boiling point?
1 atm = 100°C
It can form a regular repeating 3D structure called a crystal lattice
Crystalline
It can aggregate with no particular long range order.
Amorphous Solids
It is higher in solute, lower in solvent.
Concentrated solution
It is lower in solute, higher in solvent.
Dilute
It is being dissolved.
Solute
It is the dissolving medium.
Solvent
High solute
Hypertonic
Low solute.
Hypotonic
