Combined gas law
when we put Boyle's law, Charles' law, and Gay-Lussac's law together, we come up with the combined gas law, which shows that: Pressure is inversely proportional to volume, or higher volume equals lower pressure. Pressure is directly proportional to temperature, or higher temperature equals higher pressure.
Stoichiometry
VSEPR
Valence shell electron pair repulsion theory is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms.

Kelvin to celsius

Molarity
Empirical formula
Solubility
the ability for a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. The resulting solution is called a saturated solution.
Hybridization
is the idea that atomic orbitals fuse to form newly hybridized orbitals, which in turn, influences molecular geometry and bonding properties.
1st Law of Thermodynamics
total energy lost/gained is equal to the total energy gained/lost by its surrounding system. ΔE=q+w
Polarity
Hess' law
states that regardless of the multiple stages or steps of a reaction, the total enthalpy change for the reaction is the sum of all changes. This law is a manifestation that enthalpy is a state function.
Heisenberg uncertainty principle
states that it is impossible to know simultaneously the exact position and momentum of a particle. That is, the more exactly the position is determined, the less known the momentum, and vice versa.
Kinetic
motion KE=1/2mv^2
One mole of an ideal gas has a volume of
22.4 litres at STP
Shielding effect
describes the attraction between an electron and the nucleus in any atom with more than one electron shell. Shielding effect can be defined as a reduction in the effective nuclear charge on the electron cloud, due to a difference in the attraction forces of the electrons on the nucleus.
Molar mass from gas law data
Nonelectrolytes
nonelectrolytes do not dissociate into ions in solution; nonelectrolyte solutions do not, therefore, conduct electricity.
Nuclear Equations
Orbital notation
Density
is an intensive property- does depend on the amount. ex: heat.
Percent Yield
what you got/what you should've gotten
Balancing equations
Gamma
Manometer
an instrument that uses a column of liquid to measure pressure, although the term is currently often used to mean any pressure measuring instrument.
Electrolytes
are salts or molecules that ionize completely in solution. As a result, electrolyte solutions readily conduct electricity
Calculating delta H using bond energies
Chemical Change
molecules change
Hund's rule
every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
kinetic molecular theory
describes a gas as a large number of submicroscopic particles (atoms or molecules), all of which are in constant rapid motion that has randomness arising from their many collisions with each other and with the walls of the container.
Quantum numbers
refer to the outermost valence electrons of the Carbon (C) atom, which are located in the 2p atomic orbital, are; n = 2 (2nd electron shell), ℓ = 1 (p orbital subshell), mℓ = 1, 0 or −1, ms = ½ (parallel spins).
Exothermic
expulsion of heat.
From fahrenheit to celsius
F=9/5 (C) + 32
Energy
the capacity to do work or make heat
Pauli exclusion principle
two or more identical fermions (particles with half-integer spin) cannot occupy the same quantum state within a quantum system simultaneously.
Concentration
molarity/Liters
Acid base titration calculation
Beta
Beta decay is the loss of a β-particle (a high energy electron).
Gas Law
equal volumes of all ideal gases (at the same temperature and pressure) contain the same number of molecules.
Molecular geometry
Endothermic
absorption of heat.
Descriptive chemistry - the halogens
a group in the periodic table consisting of five chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
