CHEM 103 EXAM 2 QUESTIONS AND
ANSWERS WITH COMPLETE
SOLUTIONS 100% CORRECT!!!
stoichiometric ratio -ANSWER ✔✔the ratio of the number of moles of one
reactant or product to another reactant or product or product
limiting reactants -ANSWER ✔✔one or more reactants are completely
consumed in the chemical reaction
theoretical yield -ANSWER ✔✔the amount of product predicted from
stoichiometry taking into account limiting reagents
percent yield -ANSWER ✔✔-relates the actual yield to the theoretical yield
- (actual yield / theoretical) x 100
concentration -ANSWER ✔✔is used to designate the amount of solute dissolved
in a given quantity of solvent
Molarity -ANSWER ✔✔(moles of solute/ Liters of Solution)
Solution -ANSWER ✔✔- homogeneous mixture
Solute -ANSWER ✔✔- one or more substances dissolved in the solvent
Solvent -ANSWER ✔✔- the component that determines the phase of the
solution
- Ex) water (most common)
, Polar molecule -ANSWER ✔✔- partial charge
Electrolyte -ANSWER ✔✔- conduct electricity - cuz solute is dissolved as ions
- Ex) ionic compounds - cuz will break up into ions
strong electrolyte -ANSWER ✔✔- completely dissociate in water
weak electrolyte -ANSWER ✔✔- partially dissociate in water = moderate to
poor conductors of electricity
- Ex) acetic acid
Nonelectrolyte -ANSWER ✔✔- do not conduct electricity - cuz solute dissolves
as a molecule
- Ex) molecular compounds (CH3CH2OH)
precipitate -ANSWER ✔✔an insoluble solid formed by a reaction in solution
solubility -ANSWER ✔✔The amount of that substance that can be dissolved in
a given quantity of solvent
strong acid -ANSWER ✔✔completely ionize in solution
weak acid -ANSWER ✔✔partially ionize in solution
Oxidation-Reduction reactions -ANSWER ✔✔- where electrons are transferred
from one substance to another
