In a displacement reaction, which metal will displace another?

• A less reactive metal will displace a more reactive metal.

• A more reactive metal will displace a less reactive metal.

• Metals do not displace each other.

• Displacement depends on the temperature.

What is the main reason for using displacement reactions in the extraction of metals?

• They are cost-effective.

• They produce less pollution.

• They are faster than other methods.

• They allow extraction of metals from their compounds.
