if you are good at it let me know 

·         Ideal gas law

·         Use units

§  Volume in Liters

§  Pressure in Atmospheres

§  Temperature in Kelvins

§  Quantities in Moles

·         Molar volume at STP is 22.4 L/mole

§  STP Standard Temperature and Pressure

·         Standard Pressure = 1 Atm

·         Standard Temperature = 0 °C or 273.15 K

·         Dalton’s law of partial pressure

·         Partial pressure

·         Mole fraction

·         Partial pressure from total pressure and mole fraction

·         Collecting gases over water

§  Remove vapor pressure of water before doing stoichiometry

·          Gas phase Stoichiometry

·         Remember find moles first then do stoichiometry then go back to volume or mass depending on what is asked.

·         Remember “Limiting Reagents” problems

§  Theoretical yield

§  Actual  yield

 

§  Percent yield

 

 ·         For a given temperature lighter substances travel at greater velocity than heavier substances. Therefore, lighter substances have broader velocity distributions than heavier ones at a given temperature.

 

§  You should be able to determine lighter substances from heavier one from their distribution curve.

 

·         Graham’s law of effusion

Rate is inversely proportional to square-root of molecular mass

·         Difference between Kinetic and Potential Energy

·         Units of energy

·         First Law of Thermodynamics

·         Conservation of Energy

§  Total energy of the universe is constant

§  No free lunch

§  Thermodynamically the universe can be divide into the System (under study) and the Surroundings (everything not the system)

 

·         State functions

·         Electron Configuration: How electrons Occupy Orbitals

·         Be familiar how electrons are addressed within an atom.

·         Sublevels in multi-electron atoms are split in terms of energy. Should be familiar, I will provide orbital energy diagram for exsam.

·         Be familiar with the Aufbu build up principle.

·         Distinguish between core and valence electrons.

§  Valence electrons is where the fun happens.

·         The quantum-mechanical model explains the behavior of atoms within the periodic table.

§  Be familiar with period trends such as

·         Atomic radii

·         Atomic radii tend to decrees as we move from left to right along and period

·         Increase as we move down a group (or family)

·         In general atomic cations (positive charge) are smaller than their corresponding neutral atoms

·         Anions tend to be larger than their neutral atoms

§  Be familiar with what distinguishes paramagnetic species from diamagnetic species

·         Hint: unpaired electrons

§  Be familiar with trends in first ionization energy.

·         Tends to increase from left to right across a period

·         Due to electrons attraction to increasing nuclear charge

·         Tends to decrees as we move down a group (or family)

·         Due to electrons decreased attraction as effective nuclear charge diminishes.

 

§  Be familiar with trends in metallic character.
