  1. 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.


  1. 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?
