A full valence shell AND opposite sign of charge
What does VSEPR stand for?
Valence Shell Electron Pair Repulsion
The system's temperature is decreasing. It is an _________ reaction.
Exothermic
Spontaneity is determined by these factors. (Must state all factors)
∆H, T, and ∆S (enthalpy change, temperature, and entropy change)
Rory
This is the name of the diagram used to represent covalent compounds and their valence electrons
Lewis structures (or lewis dot diagram)
These intermolecular forces arise from polar bonds and asymmetry in molecules
This is the specific heat capacity of water.
4.18 J K-1 mol-1
This is the physical state with the highest entropy value.
Gaseous state
This danish scientist bears a striking resemblance to someone in A block HL1 Chem.
Niels Bohr
This is a factor which influences the strength of London Dispersion Forces
Size of atom (more e- means more temporary dipoles) OR shape of molecule (more contact b/w molecules = the higher the force of attraction)
Bent
This is carbon's enthalpy of formation in graphite.
0 kj/mol
Ammonium nitrate dissolves in water. It is a spontaneous endothermic process because the system undergoes this change in entropy.
At the beginning of the year, I asked you all to rank the following fantasy/sci-fi series: Star Wars, Harry Potter, Lord of the Rings. How did grade 11 chemists rank them (in order of most liked to least).
Harry Potter, Star Wars, Lord of the Rings
This is the measure of the tendency of an atom to attract a bonding pair of electrons.
Electronegativity
3 bonds, 1 lone pair corresponds to this type of shape AND an example of this kind of molecule is... (Draw the molecule)
Trigonal pyramidal; any reasonable example with drawing.
The reaction below is an example of this kind of enthalpy:
1/2 Cl2(g) ---> Cl(g)
Enthalpy of atomization
If ∆H is positive, ∆S is negative, is the reaction spontaneous or not? Consider the factors that affect spontaneity.
Not spontaneous
This high street restaurant is a favorite among G11 chemists.
Din Tai Fung
This is the intramolecular bond found in a nitrogen molecule
triple bond
This is the hybridization of the carbonate ion.
sp2
When 1 mole of gaseous ions dissolves in sufficient water to give an infinitely dilute solution, it is considered this type of enthalpy.
Enthalpy of hydration
For a reaction, with Ka= 4.2 x 10-2, at equilibrium, what is the value of ∆G?
∆G = 0
For A Block: This person in our class said they enjoy choir and tap dancing. (at least, they told me they did)
For B Block: This former member of our class said that music was a big part of what they do outside of class (violin, casual singing and piano).
A block: Beatriz
B block: Chloe V.
