MO Theory
These are the terms for substances that are attracted/repelled, respectively, by magnetic fields, and which is which.
What is paramagnetic = attracted and diamagnetic = repelled?
What is L*atm*mol-1*K-1?
This is what the acronym for this theory is, expanded.
What is Valence Shell Electron Pair Repulsion Theory?
This hybridization on the central atom is analogous to a linear electron geometry
What is sp?
This is the name of the 'X' in Raoult's Law and its formula.
What is the mole fraction and "moles solvent / moles solution"?
This is an element that exists in diatomic, gaseous form in ambient conditions thats property of paramagnetism cannot be explained by Lewis Valence Theory but CAN be explained by MO Theory
What is oxygen?
The units for this phenomenon, which are directly proportional to molecular speed (i.e. slower molecular speed would result in a lower reading for this particular value), as it is ALWAYS to worked with for the IGL.
What is temperature in Kelvin?
Draw two Lewis structures of (constitutional) isomers of XeF2Cl2, one that is polar and the other that is nonpolar
See board
These relations btw two atoms on the same molecule NEVER hybridize.
What are pi bonds?
This is the percentage sum of all of the gases that make up our atmosphere (nitrogen, oxygen, argon, etc.)
How much is 100%?
This is the MO diagram for Ca2, whether it is paramagnetic or diamagnetic AND an explanation of what the bond order means for this molecule.
0.0, diamagnetic.
Extra 100 points if a "proof" is shown.
What is inversely proportional and see Dr. Harrison's trick.
This is the molecular geometry of xenon tetrafluoride and the angles btw each bond.
What is square planar, 90º?
This is the hybridization of the central atom in SiCl4
What is sp3?
The stopcock connecting a 3.89 L bulb containing argon gas at a pressure of 9.65 atm, and a 2.99 L bulb containing krypton gas at a pressure of 2.91 atm, is opened and the gases are allowed to mix. Assuming that the temperature remains constant, the final pressure in the system is this value.
Extra points: convert to mmHg.
How much is 6.72atm?
Multiply 760 * 6.72 for other answer
This is a filled-out MO diagram for Ne2, its bond order and what the bond order signifies.
What is zero, therefore this bond will not form?
It is desired to inflate a baggie with a volume of 838 milliliters by filling it with krypton gas at a pressure of 0.686 atm and a temperature of 302 K. This is how many grams of Kr gas that are needed.
How much is 1.94g?
This is the electron geometry of XeF6
This phenomenon stabilizes/balances out molecules that have non-zero formal charges, as well as an example of a molecule wherein this phenomenon is at play.
What is resonance?
Ozone, polyatomic ions.
A gas mixture contains 6.53 mol of carbon monoxide and 2.63 mol of oxygen gas.
Compute the mole fraction of CO in the mixture.
How much is 0.713?
This is the n = 2 MO diagram in order of increasing energies.
sigma 2s (1) < anti-sigma 2s (1) < pi 2p (2) < sigma 2p (1) < anti-pi 2p (2) < anti-sigma 2p (2)
At this temperature (in °C), one liter of C2H2 would have a mass of 1.061 g, if the gas pressure is 0.8460 atm. Assume that the gas behaves ideally.
How much is -20ºC?
This is a category of molecules that have a partially vacant orbital; there is an unpaired electron
What are radicals?
This is a molecule where the hybridization and the electron geometry do not correlate.
What is trick question?
(possibly something w xenon)
C2H2 + 2H2 --> C2H6.
The initial pressure of a mixture of C2H2 and an excess of H2 in a rigid vessel is 0.672 atm. A catalyst is introduced. After the reaction reaches completion, the temperature is restored to its initial value. The final pressure in the vessel is 0.462 atm.
What was the mole fraction of acetylene in the original mixture?
How much is 0.156?
