  1. The metals from potassium to lead displace hydrogen from dilute strong acids
    with decreasing reactivity.
    a) The reaction of potassium is explosive.
    b) The reaction of magnesium is vigorous.
    c) The reaction of iron is steady.
    d) The reaction of lead is slow.
  2. The metals from copper to gold do not displace from strong dilute acids.
