Figure 3
- According to Figure 1, during Reaction 1 with a magnetic field, the % PM observed at 20 mins was approximately:
A. 40%.
B. 35%.
C. 25%.
D. 20%.
- Suppose that during Reaction 3 with a magnetic field, the magnetic field had been removed at time = 5 min. Three minutes later, at time
= 8 min, the % PM would most likely have been:
F. greater than 60%.
G. between 40% and 60%.
H. between 20% and 40%.
J. less than 20%.
- According to Figure 2, in Reaction 2, how did the removal of the magnetic field affect the yield of pure metal at time = 20 min? The
yield obtained without a magnetic field was about:
A. the yield obtained with a magnetic field.
B. the yield obtained with a magnetic field.
C. times that of the yield obtained with a magnetic field.
D. 3 times the yield obtained with a magnetic field.
