Electrolyte
A substance that conducts a current when dissolved in water
Solvated
Surrounded by water molecules
Molecular Equation
Shows all reactants and products as if they were intact, undissolved compounds
Total Ionic Equation
Shows all soluble substances dissociated into ions
Net Ionic Equation
Shows the actual chemical change (elimination of spectator ions)
Precipitation Reaction
Two soluble ionic compounds react to form and insoluble produce (precipitate)
Metathesis Reaction
Double-Displacement Reaction
Oxidation-Reduction (Redox) Reaction
Reaction with a net movement of electrons from one reactant to the other. Driving force is from the reactant with less attraction for electrons to the reactant with more attraction for electrons.
Electron Transfer
Behavior in a redox reaction that forms and ionic compound
Electron Shift
Behavior in a redox reaction that results in a polar molecule
Boyle's Law
Volume and Pressure
Charles's Law
Volume and Temperature
Avogadro's Law
Volume and Moles
Mole Fraction
One component's fraction of moles in a mixture
Root-Mean-Square Speed
(3RT/M)^(1/2)
Rate of Effusion or Diffusion
Rate1/Rate2 = (Molarity2/Molarity1)^(1/2)
van der Waals Equation
Adjusts pressure up and volume down to account for intermolecular attraction and molecular volume.
Thermodynamics
The study of heat and its transformations
E
Internal Energy
Heat
q; energy transfer due to difference in TEMPERATURE
Work
w; transfer of energy by force
Law of Conservation of Energy (First Law of Thermodynamics)
The total energy of the universe in constant
Pressure-Volume Work
Type of work in which a volume changes against an external pressure
State Function
A property dependent only on the current state of the system, NOT the path the system took to get to that state
Enthalpy
H; At constant pressure, this eliminates the need to consider PB work. E + PV
Heat of Reaction
H(final) - H(initial)
Heat Capacity
The quantity of heat required to change the temperature of 1 GRAM of a substance by 1 K
Heat absorbed or released (formula)
q = c * m * change in T
Thermochemical Equation
A balanced equation that states the heat of reaction
