Atoms that lose electrons are Oxidized.
Atoms that gain electrons are Reduced.
Electrochemical devices - Correct Answer Systems that control the electron transfers in Redox
processes.
Thermodynamic stability - Correct Answer Measure of how stable a system is with respect to changes in
the surroundings. *****
Galvanic Cell - Correct Answer Spontaneous= No energy input needed, makes energy.
Delta G= (-), Product favored
To increase sell potential:
- Make Delta G more negative
- Increase Surface Area
Electrolyte - Correct Answer Conducts electricity in dissolved form (ex: Salt).
Compound - Correct Answer Two or more chemical elements are bonded.
Element - Correct Answer Substance of atoms that all have the same number of protons.
Homogeneous mixture - Correct Answer A homogeneous mixture has the same uniform appearance
and composition throughout.
Heterogeneous mixture - Correct Answer A heterogeneous mixture is composed of non-uniform
molecules or they have localized regions that all have different properties.
, Chemical change - Correct Answer Any change that results in the formation of a new chemical
substance.
Physical change - Correct Answer Rearrangement of molecules that does not effect their chemical
makeup.
Law of conservation of mass - Correct Answer
Kinetic stability - Correct Answer
Endothermic - Correct Answer Process of electrons moving from Low potential energy to High potential
energy. Gaining heat/energy.
Ex:
Exothermic - Correct Answer Process of electrons moving from high potential energy to low potential
energy. Release of heat/energy.
Ex:
Energetic factors - Correct Answer Energetic stability increases with decreasing potential energy.
