(MLW) MVA Year 9 Chemistry Displacement Reactions Quiz

What is used to predict the outcome when metals are added to solutions of metal compounds?

• Reactivity series

• Rust analysis

• Displacement reactions

• Metal combinations

What happens when iron is added to a solution of copper sulfate?

• The solution turns blue.

• The iron nail rusts.

• Copper displaces iron.

• Iron displaces copper.

What is the pinkish/brownish colour that appears on the iron nail when added to copper sulfate solution?

• Rust

• Copper

• Iron sulfate

• Magnesium

What type of reaction occurs when iron displaces copper in the solution?

• Oxidation

• Reduction

• Combination

What are the two new products formed in the reaction between iron and copper sulfate?

• Zinc and magnesium

• Copper and iron sulfate

• Gold and silver

• Iron and copper sulfate

What is the word equation for the reaction between iron and copper sulfate?

• Iron + Copper sulfate → Iron sulfate + Copper

• Copper + Iron sulfate → Iron + Copper sulfate

• Iron sulfate + Copper → Copper sulfate + Iron

• Copper sulfate + Iron → Copper + Iron sulfate

Why does no reaction occur when copper is added to iron sulfate?

• Copper is more reactive than iron.

• Copper is less reactive than iron.

• Copper displaces iron.

• Iron is more reactive than copper.

How can displacement reactions help arrange metals into a reactivity series?

• By forming new compounds

• By analyzing rust

• By observing color changes

• By showing which metal displaces another
