constant representing the charge on one mole of electrons; 96,485 coulombs
miscible
liquids that dissolve completely in one another
(John) Dalton
Scientist who theorized elements, compounds, and that atoms are never created or destroyed
Henri Becquerel
Found uranium spontaneously emits high-energy radiation.
complex ions
compound with transition metal in center and molecule like NH3 attached to it?
dipole moment
quantitative measure of the magnitude of a dipole
When oxygen is in a peroxide is
-1
isomers
species with the same formula but different properties
cation
positively charged ion, occurs when an atom loses electrons
titration
a technique used to determine the concentration of a solution
Dark
When energy is absorbed, the absorbed energy shows up as a ---- area on absorption spectrum
Anion and Cation effects Atomic Radii
cations:smaller; anions:bigger
binary compound
compounds formed from just two elements
gamma radiation
high energy form of light- most dangerous
fossil fuels
fuels that have formed over millions of years from the decomposition of plants and animals, majorly used are coal, petroleum, and natural gas
coordination compound
compound composed of complex ion and counter ions sufficient to give no net charge
chemical properties
describe the way a substance may change or react to form other substances; for e.g. flammability
supercooling
the process of cooling a liquid below its freezing point without its changing to a solid. (10.8)
electronegativity
how strongly the nucleus of an atom attracts the electrons of other atoms in a bond (inc across, dec down)
scientific notation system
an exponential means of expressing figures
90% of the compounds we know of are...
molecules
second order rate law
1/[A]t - 1/[A]o = kt
Addition Reactions
A simple molecule or an element is added to another molecule
noble gases
group 8A, nonmetals that are gases at room temperature, monoatomic, high radioactivity of Rn, completely filled s and p subshells, large first ionization energies - decrease as we move down the column, exceptionally unreactive due to stable electron configurations
Hund's rule
when an electron is added to a subshell, it will always occupy an empty orbital if available
conjugate acid
species formed when proton is added to base
mass defect
the change in mass occurring when a nucleus is formed from its component nucleons. (18.5)
law of definite proportion
a given compound always contains exactly the same proportion of elements by mass.
Significant Figures
The digits in a measured number that include all certain digits and the first uncertain digit.
Millikan's oil drop experiment
gave evidence for the
charge of the electron
intensive properties
do not depend on the amount of the sample
half reaction for Water
2H2O --> O2 + 4H + 4e
Pauli Exclusion Principle
No two electrons within the same atom can have the same set of quantum numbers
Standard free energy of formation
the change in free energy that accompanies the formation of one mole of a substance from its constituent elements with all reactants and products in their standard states.
Powerful Reducing Agents in Base
So3^2- turns to SO4^2- (colorless to colorless)
de Broglie equation
= λ = h/ mv
λ= wavelength
m = mass of particle
v = speed of particle
mv= p = momentum of particle
h= plank's constant
* structurally not a mono or polymer* Insoluble in water (hydrophobic / non-polar)* C,H & O* Classes - triglycerides (long term E), phospholipids (PM), eicosanoids (chem signals), waxes (waterproofing), steriods/cholesterol (hormones/membranes)
Three types of Fatty Acids
How to find the amount of electromagnetic radiation released when electrons jump to lower energy levels?
ΔE = hv = hc/λ

λ= wavelength of the radiation (0.0000001m = 100nm)
h= 6.63x10^-34 joule-sec
v= frequency of radiation
c= 3.00x10^8 m/sec (speed of light)
/ 58
