Reactivity Series & Displacement Reaction

What is the measure of how reactive a metal is?

• Number of neutrons

• Tendency to lose electrons

• Atomic mass

• Number of protons

Which metal is more reactive - one high up or one lower down on the reactivity series?

• One high up

• One lower down

• Both are equally reactive

• Depends on the metal

What happens in a displacement reaction between metals and aqueous solutions of metal salts?

• Both metals lose electrons

• The more reactive metal gains electrons

• The less reactive metal is reduced

• The metals form a new compound

What does OIL-RIG stand for in the context of metal displacement reactions?

• Oxidation is loss of ion - Reduction is gain of ion

• Oxidation is loss of electron - Reduction is gain of electron

• Oxidation is gain of electron - Reduction is loss of electron

• Oxidation is gain of ion - Reduction is loss of ion

In the reaction between magnesium and copper sulfate, what is formed?

• Magnesium + copper sulfate

• Magnesium + copper

• Magnesium sulfate + elemental copper

• Magnesium sulfate + copper

What happens to the blue color of the copper sulfate solution in the magnesium + copper sulfate reaction?

• It changes to red

• It fades

• It turns green

• It becomes more intense

What is the role of the less reactive metal in a displacement reaction?

• It gains electrons

• It loses electrons

• It forms a new compound

• It is reduced

Which metal will displace another metal from a solution of one of its salts?

• The more reactive metal

• Depends on the salt

• The less reactive metal

• Both metals equally

What happens to the more reactive metal in a displacement reaction?

• It forms a new compound

• It disappears from the solution

• It loses electrons

• It gains electrons

What is the main difference between a more reactive and less reactive metal in a displacement reaction?

• Tendency to gain electrons

• Number of protons

• Tendency to lose electrons

• Atomic mass
