(Revision) Using reactivity series and displacement reactions

Which metal can displace zinc from zinc sulfate solution?

• Copper

• Iron

• Magnesium

• Silver

What happens when calcium reacts with copper sulfate solution?

• No reaction occurs

• Calcium sulfate and copper are formed

• Calcium displaces copper, forming calcium nitrate

• Copper remains unchanged

Why does silver not react with hydrochloric acid?

• Silver is very reactive

• Silver is less reactive than hydrogen

• Silver reacts only with strong bases

• Silver forms a complex with the acid

Which of these is the correct product of heating zinc oxide with carbon?

• Zinc and carbon dioxide

• Zinc carbonate

• Carbon monoxide and zinc

• No reaction occurs

Which of these metals is extracted by displacement using zinc sulfate?

• Iron

• Lead

• Gold

• Calcium

Which reaction will occur when magnesium is added to a solution of zinc sulfate?

• Magnesium sulfate and zinc are formed

• No reaction occurs

• Zinc magnesiumate is formed

• Zinc sulfate and magnesium remain unchanged

What are the products of heating copper(II) oxide with carbon?

• Copper and carbon monoxide

• Copper and carbon dioxide

• Copper carbonate and carbon

• No reaction

Which of the following explains why gold does not corrode in moist air?

• Gold is highly reactive

• Gold is less reactive than oxygen

• Gold reacts only with acids

• Gold is unreactive due to its position in the reactivity series

What is the role of carbon in extracting metals from their oxides?

• Oxidizing agent

• Reducing agent

• Catalyst

• Inhibitor

Which metal will not displace iron from iron sulfate solution?

• Zinc

• Magnesium

• Copper

• Calcium
