2. Which of the following statement about this class is false?
A) Each students gets to drop their lowest regular exam grade, but the final grade
(adjusted to 100 pts) would then replace that missing score.
B) If a student bombs the final, they don’t have to use it to replace their lowest regular
exam grade, but their class grade will drop a lot because the final is ¼ of the final grade.
93% correct C) The Mastering Chemistry homework is there only to earn
points towards a final grade. It doesn’t matter if the students understand the
questions and their answers or not.
D) The supplemental (extra credit) homework must be done in a very specific way to
earn credit.
E) Students are expected to learn part of the more straightforward material from the
textbook on their own.
3. For the following reaction, which of the following changes would shift the equilibrium to the
left?
CH3CH=CH2 + H2O CH3CHOHCH3 +
heat
A) Adding excess water
72% correct B) Removing water
C) Adding more CH3CH=CH2
D) Removing CH3CHOHCH3

, 53% correct A) there are no hydrogen atoms attached to the alcohol carbon.
B) the alcohol carbon is bonded to four groups so no oxygen can be added to it. No O is
added, H is removed (and there isn’t one)
C) the alcohol carbon is too electronegative to have hydrogen removed from it.
D) there are no oxygen atoms to remove from the alcohol carbon.
E) the alcohol carbon is bonded to four groups so no hydrogen can be added to it.
Oxidation, not addition reaction
