ACS Chemistry Final (general chem 1 review)
questions and answers Graded A+
Density - ✅✅mass / volume
Conversion from celsius to kelvin - ✅✅K = DegC + 273.15
Conversion from DegF to DegC - ✅✅DegC = (5/9) (DegF - 32)
Conversion from DegC to DegF - ✅✅DegF = (9/5)(DegC) + 32
Intensive properties - ✅✅Independent of amount of matter examined
Extensive propertires - ✅✅Dependent of amount of matter examined
Alcohol - ✅✅compund in which an H atom of a hydrocarbon is replaced by an
OH funxtional group (alcohols end in -ol)
Formula weight - ✅✅sum of the atomic weights of each atom in its chemical
formula
Percent composition - ✅✅% element = (number of atoms of that
element)(atomic weight of element) / formula weight of compound
Avogadro's number - ✅✅6.02x10^23
, Molar mass - ✅✅The molar mass (g/mol) of any substance is always
numerically equal to its formula weight (in amu)
limiting reagent - ✅✅the reactant that is completely consumed in a reaction
Percent yield - ✅✅Percent yield = actual yield / theoretical yield x 100%
Actual yield = amount of product actually obtained in a reaction
electrolyte - ✅✅A substance whose aqueous solutions contain ions
Strong electrolytes - ✅✅solutes that exist in solution completely as ions
Solubility of compunds containing NO3-, CH3COO-, Cl-, Br-, I-, SO42- -
✅✅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- - ✅✅Insoluble in all
except S2-, and OH-: compounds of NH4+, the alkali metal cations, and Ca2+,
Sr2+, and Ba2+
