2.30 describe how reactions with water and dilute acids can be used to deduce the following order of reactivity: potassium, sodium, lithium, calcium, magnesium, zinc, iron and copper

potassium, sodium, lithium and calcium all react with water and acids
magnesium, zinc and iron all react with acids (and very slowly with water.)
copper doesn't react with either.

The more vigorous the reaction the more reactive the metal. The more things a metal will react with, the more reactive the metal.

  3. magnesium, zinc and iron won't react much with cold water but they will react with steam.

  4. Is their a temperature change for the more reactive metals

  5. You forgot to mention that all of them react with oxygen (-;
