"Taking Luxurious Limos More Noxious Than Cycling"

Temperature (K)
Length (m)
Luminous intensity (Cd)
Mass (kg)
Number of particles (moles)
Time (s)
Charge (C)

"Quintessential Curriculum Vitae"

Q=CV

"England Hails Queen Victoria"

E(energy stored) = 1/2 QV

Front 3

Elastic Modulus

Back 3

"Essay"

Elastic modulus = stress/strain
I.e. "es"/"ai" or "essay"

Stress is associated with the forss(force) applied.
Strain is the deformation produced.

Electromagnetic Spectrum

Back 4

"RIVUXGa"

Electromagnetic waves in order of increasing frequency:

Radio waves
Infra red
Visibile spectrum
Ultra violet
X-rays
Gamma rays

Fore on a Charge Moving in a Magnetic Field

Back 5

"Fast Quality Vitalizes Business"

F = QvB
(N = C x m/s x T)
i.e., if the direction of travel is perpendicular to the magnetic field

Front 6

Heat Capacity

Back 6

"MCAT"
q=mcdT

where q is heat energy, m is mass, c is specific heat capacity, and dT is the change in Temperature

Optics

Back 7

"D DUV"

For Divrging mirros and lenses, the image is always Diminished, Upright, and Virtual, regardless of the distance of the object from the mirror or lens

Bonding

Back 9

"HONC"

H requires 1 more electron in its outer shell to become stable.
O requires 2
N requires 3
C requires 4

Front 10

Cation

Back 10

The "t" in cation looks like a plus sign: "ca+ion"

Front 11

Electrochemistry

Back 11

Reduction occurs at the Cathode: Oxidation at the Anode

Remember that the terms beginning iwth consonants are together, and those beginning with vowels are together

"LEO is a GERC (jerk)"

Loss of Electrons is Oxidation, which occurs at the Anode. Gain of Electrons is Reduction, which occurs at the Cathode.

"MIT enough"

Moles deposited at an electrode = It/nF

Gobb's Free Energy

Back 13

"Good Honey Tastes Sweet"

ΔG = ΔH - TΔS

"Gee! Plus Arty! Thank you!"

ΔG = ΔG° + RTlnQ

"Delicious Grapefruit - Not For Everyone"

ΔG° = -nFE°

Henderson-Hasselbalch Equation

Back 14

"HK + AHA"
or "Hong Kong + American Hospital Association"
pH = pKa + log10(A-/HA)

Front 15

Hydrogen Bonding

Back 15

"FON"

When a hydrogen atom is attached to either a fluorine, oxygen or nitrogen atom, it can form a hydrogen bond between it and another fluorine, oxygen, or nitrogen atom.

Front 16

Nernst Equation

Back 16

"We minus Arty (is) enough, thank you"

E = E - (RT/nF)lnQ

Front 17

Paramagnetism

Back 17

If a compund has a t least one unpaired electron,
it is Paramagnetic,
and will be Pulled toward a magnetic field.

If not, it is diamagnetic, and is weakly repelled by a magnetic field. There is also a third type of magnetism: ferromagnetism, whic his present in what we casually call "magnets," e.g. iron, nickel, cobalt
