Displacement reaction

The video explains how a more reactive element can replace a less reactive one in a compound. It uses the example of copper, which is more reactive than silver, to demonstrate how copper displaces silver ions from a silver nitrate solution. The process involves copper atoms losing electrons to become ions, while silver ions gain electrons to form solid silver on copper. This reaction results in a color change of the solution from clear to blue.

What happens when a more reactive element is introduced to a compound containing a less reactive element?

• Both elements remain unchanged.

• The compound becomes unstable.

• The less reactive element is displaced.

• The more reactive element is displaced.

Why can copper displace silver ions from a silver nitrate solution?

• Copper is less reactive than silver.

• Copper is more reactive than silver.

• Copper and silver have the same reactivity.

• Silver is more reactive than copper.

What is the result of copper atoms losing electrons in the reaction?

• Copper atoms become neutral.

• Copper atoms form a gas.

• Copper atoms gain electrons.

• Copper atoms become ions.

What happens to silver ions during the reaction with copper?

• They lose electrons and form ions.

• They gain electrons and form atoms.

• They remain as ions in the solution.

• They evaporate from the solution.

What color change occurs in the solution as a result of the reaction?

• The solution turns red.

• The solution turns green.

• The solution turns blue.

• The solution remains clear.
