- A chemist claimed that separating pure metal using a magnetic field is always faster than without a magnetic field. Do Figures 1– 3
support this claim?
F. No; in Reaction 1 the % PM reached 0% sooner without a magnetic field than with a magnetic field.
G. No; in Reaction 1 the % PM reached 100% sooner without a magnetic field than with a magnetic field.
H. Yes; the % PM consistently reached 0% sooner with a magnetic field for all three reactions than without.
J. Yes; the % PM consistently reached 100% sooner with a magnetic field for all three reactions than without.
- If Reaction 3 had been graphed as percent of metal oxide (% MO) as time increases instead of % PM:
% MO = × 100
Which of the following graphs best represents how Figure 3 would have appeared?
