Question

1. this measures the amount of a product obtained from a reaction.
2. which yield comes from measurements obtained during a real experiment?

a) actual yield
b) theoretical yield
c) percent yield

1. percent yield basically means...

a) how involved the reaction is
b) how complicated the reaction is
c) how fast the reaction occurs
d) how efficient the reaction is

1. when you perform a stoichiometry calculation, you are determining the

a) actual yield
b) theoretical yield
c) percent yield

Explanation:

• For the first - unnumbered question asking what measures the amount of a product obtained from a reaction, it is yield.
• For question 29, actual yield comes from measurements in a real experiment. Theoretical yield is calculated stoichiometrically, and percent yield is a ratio of actual to theoretical yield.
• For question 30, percent yield is the ratio of actual yield to theoretical yield and represents the efficiency of a reaction.
• For question 31, stoichiometry calculations are used to determine theoretical yield.

Answer:

• 29) A. actual yield
• 30) D. how efficient the reaction is
• 31) B. theoretical yield
