Conversion from celsius to kelvin - CORRECT ANSWERS ✅✅ -K = DegC + 273.15
Conversion from DegF to DegC - CORRECT ANSWERS ✅✅ -DegC = (5/9) (DegF -
32)
Conversion from DegC to DegF - CORRECT ANSWERS ✅✅ -DegF = (9/5)(DegC) +
32
Intensive properties - CORRECT ANSWERS ✅✅ -Independent of amount of matter
examined
Extensive propertires - CORRECT ANSWERS ✅✅ -Dependent of amount of matter
examined
Alcohol - CORRECT ANSWERS ✅✅ -compund in which an H atom of a
hydrocarbon is replaced by an OH funxtional group (alcohols end in -ol)
Formula weight - CORRECT ANSWERS ✅✅ -sum of the atomic weights of each
atom in its chemical formula
Percent composition - CORRECT ANSWERS ✅✅ -% element = (number of atoms of
that element)(atomic weight of element) / formula weight of compound
Avogadro's number - CORRECT ANSWERS ✅✅ -6.02x10^23
Molar mass - CORRECT ANSWERS ✅✅ -The molar mass (g/mol) of any substance
is always numerically equal to its formula weight (in amu)
limiting reagent - CORRECT ANSWERS ✅✅ -the reactant that is completely
consumed in a reaction
, Avogadro's law - CORRECT ANSWERS ✅✅ -volume of gas maintained at constant
temperature and pressure is directly proportional to the number of moles of the gas
Charle's law - CORRECT ANSWERS ✅✅ -the volume of a fixed amount of gas
maintained at constant pressure is directly proportional to its absolute temperature

Percent yield - CORRECT ANSWERS ✅✅ -Percent yield = actual yield / theoretical
yield x 100%
Actual yield = amount of product actually obtained in a reaction
electrolyte - CORRECT ANSWERS ✅✅ -A substance whose aqueous solutions
contain ions

Molecular substances are _____ , and ____ - CORRECT ANSWERS ✅✅ -strong
electlytes and weak acids and bases
Oxidation # rules - CORRECT 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 - CORRECT ANSWERS ✅✅ -Any metal can be oxidized by the ions
of elements below it
