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