No reaction takes place.
A reaction takes place. And a colour change is observed.
- 27. Multiple Choice
Copper is less reactive than iron. What do you expect to happen when iron is placed inside a solution of copper(II) sulfate?

- 28. Multiple Choice
Which gas gives out a 'squeaky pop' when a lighted splint is placed in it?
hydrogen
oxygen
carbon dioxide
nitrogen
- 29. Multiple Choice
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.
