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