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.
