answer these questions: 1. what does the activity series tell us? 2. can a metal undergo any of the reactions listed below it in the series? 3. list two metals that cobalt will displace and two that will displace it.

answer these questions: 1. what does the activity series tell us? 2. can a metal undergo any of the reactions listed below it in the series? 3. list two metals that cobalt will displace and two that will displace it.

Answer

Brief Explanations:

  1. The activity series ranks metals by their reactivity. Metals higher in the series are more reactive and can displace those lower in reactions with metal - ion solutions or acids.
  2. A metal can undergo the reactions listed below it in the series because it is more reactive than the metals associated with those reactions.
  3. Cobalt is more reactive than metals like copper and silver, so it can displace them. Metals like zinc and magnesium are more reactive than cobalt and can displace it from its compounds.

Answer:

  1. It ranks metals by reactivity and shows which can displace others in reactions.
  2. Yes.
  3. Metals cobalt will displace: Copper, Silver. Metals that will displace cobalt: Zinc, Magnesium.
