alkanes
(alkanes! they're driving me insane)
what is a saturated hydrocarbon
100
The energy gained from movement
What is kinetic energy?
100
the particle theory of matter
All matter is made of particles
All particles have spaces in between them
Particles are always in random motion
The particles in a substance attract each other
100
sharing of electrons to form electron pairs between atoms
what is a covalent bond?

Which one is wider, Australia or the moon?
Australia!

3-hexene
200
type of reaction of elephant toothpaste
What is decomposition?

What's the difference between a graveyard and a cemetery?
A graveyard is on church ground.
300
what is a functional group, and name three
A group of atoms that define the characteristics of a molecule
Examples: -OH (alcohol), carboxyl/carboxylic acids, C=O (carbonyl), alkyl group, alkyl halides, esters,
300
Determine the type of reaction
* exothermic reaction
300
HBr + KOH -> H2O + KBr
What is neutralization?
300
polar covalent bonds
A polar covalent bond is one where the electrons between two atoms are shared unevenly
This results from the difference in electronegativity which causes electrons to gravitate more towards one atom.

What did I (Chris) do for my physics IA?
Double slit experiment
400
4-ethyl-2-octyne

Contrast Brønsted-Lowry vs. Arrhenius acid-base theory
Bronsted = bases are proton acceptors, acids are proton donors
Arrhenius = bases increase OH- concentration, acids increase H+ concentration

_C3H8 + _O2 --> __CO2 + __H2O
(+50 if you can identify type of reaction)
C3H8 + 5O2 --> 3CO2 + 4H2O

Re-arrange the following compounds in terms of highest --> lowest boiling point, and explain why you arranged it that way.
HF, CH4, NaCl, HCl
NaCl, HF, HCl, CH4

What was the colour of the initial dot that scientists placed on the belly of the cleaner fish to test whether or not they could recognize themselves in the mirror?
(double points if you can explain why)
Red!
500
draw an ester (any kind) 2 mins
answers may vary,
General formula for an ester: RCOOR’
R = hydrocarbon group from the carboxylic acid,
COO = functional group of the ester, one O is double bonded to the carbon, the other is single bonded to the carbon and to the other group (R’)
R’ = hydrocarbon group that comes from the alcohol

what is schrodingers cat?
Schrödinger's Cat is a famous thought experiment that demonstrates the idea in quantum physics that tiny particles can be in two states at once until they're observed. It asks you to imagine a cat in a box with a mechanism that might kill it. Until you look inside, the cat is both alive and dead at the same time.
The Schrodinger wave equation describes the behaviour of a particle in a field of force or the change of a physical quantity over time.

What is an instantaneous dipole moment?
A dipole moment is the product of the magnitude of the charge and the distance between the centers of the positive and negative charges.
Dipole moments are created from differences in electronegativity. The dipole moment is a measure of the polarity of the molecule
