General Chemistry 2 Final Exam
Redox Reaction - correct answers In oxidation, one atom gains electrons and one looses electrons.
Atoms that lose electrons are Oxidized.
Atoms that gain electrons are Reduced.
Electrochemical devices - correct answers Systems that control the electron transfers in Redox
processes.
Thermodynamic stability - correct answers Measure of how stable a system is with respect to changes
in the surroundings. *****
Galvanic Cell - correct answers 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 answers Conducts electricity in dissolved form (ex: Salt).
Compound - correct answers Two or more chemical elements are bonded.
Element - correct answers Substance of atoms that all have the same number of protons.
Homogeneous mixture - correct answers A homogeneous mixture has the same uniform appearance
and composition throughout.
Heterogeneous mixture - correct answers A heterogeneous mixture is composed of non-uniform
molecules or they have localized regions that all have different properties.
Chemical change - correct answers Any change that results in the formation of a new chemical
substance.
Physical change - correct answers Rearrangement of molecules that does not effect their chemical
makeup.
Law of conservation of mass - correct answers
Kinetic stability - correct answers
