Chapter 11 Key Terms

Question 1

stoichiometry

Answer 1

the study of the quantitative, or measurable, relationships that exist in chemical formulas and chemical reactions

Question 2

mole-mole problem

Answer 2

problem in which you convert from moles of one substance to moles of another

Question 3

mass-mass problem

Answer 3

problem in which you are given a mass and asked to find a mass

Question 4

mass-volume problem

Answer 4

problems in which you are given a mass and asked to find a mass [sic?], or vice versa

Question 5

volume-volume problem

Answer 5

problems in which you are given a volume and asked to find a volume

Question 6

limiting reactant

Answer 6

the reactant that limits the amount of product formed in a reaction; the quantities of product formed in a reaction are always determined by the quantity of the limiting reactant

Question 7

expected yield

Answer 7

the amount of product that should be produced based on calculations

Question 8

actual yield

Answer 8

the amount of product that is really obtained from a chemical reaction (a given or measured value)

Question 9

percent yield

Answer 9

percent of the expected yield that was actually obtained. Percent yield = (actual yield/expected yield) x 100%.
