Y8U5T5 - Determining the Reactivity Series of Metals

Which method can be used to determine the reactivity series of metals?

• Conducting displacement reactions between different metals and their compounds
• Measuring the density of metals
• Testing their electrical conductivity
• Observing their color
• Smelling their odor

In a displacement reaction, which metal will displace the other metal from a compound?

• A more reactive metal
• A less reactive metal
• Both metals simultaneously
• The metal with higher density
• The metal with higher boiling point

When iron filings are added to copper sulfate solution, what metal is formed?

• Copper
• Iron
• Zinc
• Aluminum
• Silver

What does a displacement reaction between metals and their compounds help create?

• A reactivity series of metals
• A conductivity chart
• A density scale
• A color spectrum
• An odor classification

If zinc is more reactive than copper, what will happen when zinc is added to copper sulfate solution?

• Zinc will displace copper and form solid zinc sulfate
• Copper will displace zinc and form solid copper sulfate
• Zinc and copper will combine to form a new compound
• No reaction will occur
• Zinc sulfate will decompose into zinc and copper

In the extraction of iron from its ore, what is used as a reducing agent?

• Carbon
• Oxygen
• Hydrogen
• Sulfur
• Aluminum

When carbon reacts with iron oxide during the extraction of iron, what is produced?

• Carbon dioxide gas and molten iron
• Oxygen gas and solid iron
• Water vapor and iron oxide
• Nitrogen gas and liquid iron
• Helium gas and iron sulfate

What is the purpose of using displacement reactions in metal extraction?

• To selectively remove the desired metal from its ore
• To increase the density of metals
• To enhance the color of metals
• To improve the electrical conductivity of metals
• To reduce the boiling point of metals

Which metal is more reactive, carbon or iron?

• Carbon
• Iron
• They have the same reactivity
• It depends on the conditions
• None of the above

What happens when a less reactive metal is added to a salt solution of a more reactive metal?

• No reaction occurs
• The less reactive metal displaces the more reactive metal
• The less reactive metal dissolves in the solution
• The more reactive metal becomes less reactive
• The more reactive metal precipitates out of the solution
