General Chemistry 2 Final Exam Solved
Correctly To Score A+ 2025
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
Endothermic CORRECT ANSWERS Process of electrons moving from Low potential
energy to High potential energy. Gaining heat/energy.
Ex:
Exothermic CORRECT ANSWERS Process of electrons moving from high potential
energy to low potential energy. Release of heat/energy.
Ex:
Energetic factors CORRECT ANSWERS Energetic stability increases with decreasing
potential energy.
Delta H
Features to consider:
Bond strength
Chemical composition
Charge distribution
State of matter
Intermolecular Forces
Entropic factors CORRECT ANSWERS The stability of a system increases, the larger
the number of ways the system has to distribute both its matter and energy.
Delta S
CONFIGURATIONS
Oxidation CORRECT ANSWERS Oxidation is the loss of electrons or an increase in
oxidation state by a molecule, atom, or ion.
Oxidation state: (# of valence e- on atom)-(# of bonded e- + # of lone pairs)
Increase in Oxidation #= Oxidation
Decrease in Oxidation #= Reduction
Oxidized= Charge is taken
Reduced= Charge is added
Reduction CORRECT ANSWERS Reduction is the gain of electrons or a decrease in
oxidation state by a molecule, atom, or ion.
Cathode
Ionic radius CORRECT ANSWERS Increases from left and down.
