Unit 3 Part 2

Chemistry

QuestionAnswer
Can collisions between gases be inelastic? To some extent
Intramolecular forces Bonds are inside molecules; ionic or covalent
Intermolecular forces Attraction between molecules; exist outside of the molecules
Dipole Permanent positive and negative ends of separate polar molecules
Ion-Ion Ions only
Ion-Dipole Ions and polar molecules; positive and negative bond together
Dipole-induced dipole At least one molecule must be polar
Dispersion All types of molecules
Hydrogen Bonding N, O, F bond with a Hydrogen; share the H bond
Hydrogen bonding ranked(O, N, F) N<O<F
Lattice energies from ionic bonds 800-10,000 kJ/mole
Covalent tripe bond energy 800 kJ/mole
Covalent double bond energy 600 kJ/mole
Covalent single bond energy 400 kJ/mole
Ion-Dipole energy 100 kJ/mole
Hydrogen bonding energy 20 kJ/mole
Dipole-Dipole energy 10 kJ/mole
Dipersion 1 kJ/mole
High boiling point High IMF
High heat of vapor High IMF
High gas non-ideality High IMF
High Capillary Action High IMF
High melting point High IMF
High surface tension High IMF
High evaporation Low IMF
High vapor pressure Low IMF
The stronger the imtermolecular force, the _____________________________ Stronger the liquid propery
Boiling point Sufficient energy is imparted to a liquid to break the intermolecular forces that hold molecules together in a solution; directly proportional to IMF
Viscosity "Stickiness) liquids exhibit when being poured; directly proportional to IMF
Capillary Action Tendency of a liquid to climb the walls of a capillary(tube with a thin diameter); directly proportional to IMF
Surface Tension Maintains the surface interface between a liquid and a gas; causes things to float; directly proportional to IMF
Heat of vaporization Amount of energy required for a liquid to turn into a gas; directly proportional to IMF
Vapor Pressure Amount of vapor that exists above a liquid in a closed container; inversely proportional to IMF
Evaporation IMF that holds the surface molecules together is overcome by heat applied to the system prompting surface molecules to enter the gas phase; inversely proportional to IMF
Dispersion ranking The bigger the molecule, the bigger the IMF
Dipole-Dipole ranking The larger the net dipole, the larger the IMF
Hydrogen Bonding ranking N<O<F; number of H bonds
Ionic Compounds ranking Charge density; add up the charges; lattice energy
When the temperature is low, what is more likely to be produced? Solids
Metallic Solids Malleable, ductile, lustrous, electrically and thermally conducting
Ionic Solids Hard, rigid, brittle, high melting and boiling points, those soluble in water give conducting solutions
Network Solids Hard, rigid, brittle, very high melting points, insoluble in water
Molecular Solids Relatively low melting point and boiling point; brittle if pure
Metallic Bond Bonding between metals on the left side of the period table
Ionic Bond(Solids) Metals and nonmetals Bond together
Covalent Network(solid) Bond Nonmetals that form extended chains of covalent bonds
Most solid in the world are... Covalent Network Solids
Molecular Solid Bonds Small molecule develops intermolecular attractions to the other molecules, a solid can form
Gases have the lowest... Melting point
Gas velocities vary with the inverse square of... Mass
Electronegativity Negativity goes down by _____ as you go ______ the periodic table .1, down
The smaller the molecule, the ... Smaller the amount of dispersion forces
What two elements are the most ideal? Hydrogen and Helium
Colder = Lower IMF
Warmer = Higher IMF
Dispersion Distortion of the electron cloud of an atom or molecule by the presence of nearby atoms or molecules
State functions describe... Quantitative values of a system at equilibrium
What contributes to gas non-ideality? High pressure, low temperature, small volume
Intermolecular force theory In non-polar molecules, dispersion forces result from the momentary polarization of the electron cloud
Permanent dipoles Occurs in polar molecules

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
