ACS CHEMISTRY FINAL (GENERAL CHEM 1 REVIEW) QUESTIONS ANSWERED CORRECTLY LATEST
UPDATE 2026
Density - Answers mass / volume
Conversion from celsius to kelvin - Answers K = DegC + 273.15
Conversion from DegF to DegC - Answers DegC = (5/9) (DegF - 32)
Conversion from DegC to DegF - Answers DegF = (9/5)(DegC) + 32
Intensive properties - Answers Independent of amount of matter examined
Extensive propertires - Answers Dependent of amount of matter examined
Alcohol - Answers compund in which an H atom of a hydrocarbon is replaced by an OH funxtional
group (alcohols end in -ol)
Formula weight - Answers sum of the atomic weights of each atom in its chemical formula
Percent composition - Answers % element = (number of atoms of that element)(atomic weight of
element) / formula weight of compound
Avogadro's number - Answers 6.02x10^23
Molar mass - Answers The molar mass (g/mol) of any substance is always numerically equal to its
formula weight (in amu)
limiting reagent - Answers the reactant that is completely consumed in a reaction
Percent yield - Answers Percent yield = actual yield / theoretical yield x 100%
Actual yield = amount of product actually obtained in a reaction
electrolyte - Answers A substance whose aqueous solutions contain ions
Strong electrolytes - Answers solutes that exist in solution completely as ions
Solubility of compunds containing NO3-, CH3COO-, Cl-, Br-, I-, SO42- - Answers Exceptions:
Cl-, Br- , I- : compounds of Ag+, (Hg2)2+, and Pb2+
SO4)2-: Compounds of Sr2+, Ba2+, Hg2)2+, and Pb2+
Insoluble ionic compounds: S2-, (CO3)2-, (PO4)3-, OH- - Answers Insoluble in all except S2-, and OH-:
compounds of NH4+, the alkali metal cations, and Ca2+, Sr2+, and Ba2+
Insoluble in all except CO32-, PO43-: compounds of NH4+, and the alkali metal ions
Ionic substances are _____ - Answers strong electrolytes
Molecular substances are _____ , and ____ - Answers strong electlytes and weak acids and bases
Oxidation # rules - Answers -Elemental form = 0
-montatomic ion equals its charge
-Oxygen= -2 except in peroxides ((O2)2-)
-hydrogen= +1 except when bonded to metals (-1)
-Flourine=-1 in all compounds.
Activity series - Answers Any metal can be oxidized by the ions of elements below it
Dillution equation - Answers M1V1 = M2V2
kinetic energy equation - Answers Ek = 1/2 mv^2
work equation - Answers w = F x d
internal energy equation - Answers change in energy = internal final - internal initial
Internal energy relation to heat and work - Answers change in E = q + w
state function - Answers the value of a state function depends only on the present state of the
system, not the path the system took to reach that state
pressure-volume work equation - Answers w = -P (change in V)
Enthalpy - Answers H = E + PV
Enthalpies of reaction - Answers change in H = H (products) - H (reactants)
heat equation - Answers q = Cs x m x change T
* Cs = q / m x change T
m = mass
Enthalpies of formation - Answers change in Hrxn = sum of changeHf (products) - sum of change Hf
(reactants)
