An ionic bond is formed between two atoms after they have both gained these two things.

A full valence shell AND opposite sign of charge

100

What does VSEPR stand for?

Valence Shell Electron Pair Repulsion

100

The system's temperature is decreasing. It is an _________ reaction. 

Exothermic

100

Spontaneity is determined by these factors. (Must state all factors)

∆H, T, and ∆S (enthalpy change, temperature, and entropy change)

100
This is the name of Ms Sarkawi's pet dachshund.

Rory

200

This is the name of the diagram used to represent covalent compounds and their valence electrons

Lewis structures (or lewis dot diagram)

200

These intermolecular forces arise from polar bonds and asymmetry in molecules

Dipole-dipole 
200

This is the specific heat capacity of water.

4.18 J K-1 mol-1

200

This is the physical state with the highest entropy value.

Gaseous state

200

This danish scientist bears a striking resemblance to someone in A block HL1 Chem.

Niels Bohr

300

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)

300
This shape will always result in a polar molecule.

Bent

300

This is carbon's enthalpy of formation in graphite.

0 kj/mol

300

Ammonium nitrate dissolves in water. It is a spontaneous endothermic process because the system undergoes this change in entropy.

An increase (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

400

This is the measure of the tendency of an atom to attract a bonding pair of electrons.

Electronegativity

400

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.

400

The reaction below is an example of this kind of enthalpy:

1/2 Cl2(g) ---> Cl(g)

Enthalpy of atomization

400

If ∆H is positive, ∆S is negative, is the reaction spontaneous or not? Consider the factors that affect spontaneity.

Not spontaneous

400

This high street restaurant is a favorite among G11 chemists.

Din Tai Fung

500

This is the intramolecular bond found in a nitrogen molecule

triple bond

500

This is the hybridization of the carbonate ion.

sp2

500

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

500

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).
