A more reactive metal will displace a less reactive metal from a metal compound. Which metal is more reactive - copper or iron?

• copper

• iron

Which equation correctly shows the displacement of copper from copper(II) sulfate by zinc?

• copper + zinc sulfate --> copper(II) sulfate + zinc

• zinc sulfate + copper --> copper(II) sulfate + zinc

• copper(II) sulfate + zinc --> zinc sulfate + copper

• copper(II) sulfate + zinc --> zinc sulfate + water

Which equation correctly shows magnesium displacing copper from it copper(II) sulfate?

• 2Mg + O₂ --> 2MgO

• Mg + CuSO₄ --> MgSO₄ + Cu

• Mg + MgSO₄ --> MgSO₄ + Mg

A copper coil is placed inside a solution of silver nitrate. What would you expect to see after 5 minutes? Choose 2 options.

• There is no visible change because no displacement reaction took place. Copper, being less reactive than silver, cannot displace silver from silver nitrate.

• 
• 
• Silver crystals were formed on copper coil, because copper (being more reactive than silver) displaced silver from silver nitrate.
