Chem 134 Exam 2 Questions &
Answers (Grade A+)
stoichiometry -
correct answer ✅the numerical relationships between chemical
amounts in a balanced chemical equation are called reaction
stoichiometry
limiting reactant -
correct answer ✅the reactant that limits the amount of product in
a chemical reaction
theoretical yield -
correct answer ✅the maximum amount of product that can be
made in a chemical reaction based on the amount of limiting
reactant
actual yield -
correct answer ✅the amount of product actually produced by a
chemical reaction
percent yield -
correct answer ✅the percentage of the theoretical yield that was
actually attained, is calculated as the ratio of the actual yield to the
theoretical yield
,Chem 134 Exam 2 Questions &
Answers (Grade A+)
solution -
correct answer ✅a homogeneous mixtures of two substances

correct answer ✅the majority of the mixture
solute -
correct answer ✅the minority of the mixture
aqueous solution -
correct answer ✅one in which water acts as the solvent
dilute solution -
correct answer ✅one that contains a small amount of solute
relative to the solvent

, Chem 134 Exam 2 Questions &
Answers (Grade A+)
molarity -
correct answer ✅the amount of solute (in moles) divided by the
volume of solution in (liters)
stock solutions -
correct answer ✅to save space in storerooms, laboratories often
store solutions in concentrated forms called stock solutions
electrolytes -
correct answer ✅substances that dissolve in water to form
solutions that conduct electricity
strong electrolytes -
correct answer ✅substances such as sodium chloride that
completely dissociate into ions when they dissolve in water are
strong electrolytes
nonelectrolytes -
correct answer ✅compounds such as sugar that do not dissociate
into ions when dissolved in water are called nonelectrolytes
