Questions and Answers

What is a displacement reaction?

  • A chemical reaction in which a non-metal displaces a metal from its compound
  • A chemical reaction in which a more reactive element displaces a less reactive element from its compound (correct)
  • A chemical reaction in which two equally reactive elements exchange their positions in a compound
  • A chemical reaction in which a less reactive element displaces a more reactive element from its compound

    • How is the chemical reactivity of metals linked with their position in the electrochemical series?

  • Chemical reactivity of metals is linked with their atomic number
  • Chemical reactivity of metals is linked with their relative positions in the activity series (correct)
  • Chemical reactivity of metals is linked with their density
  • Chemical reactivity of metals is linked with their melting point

    • What elements can take part in displacement reactions?

  • Both metals and non-metals (correct)
  • Only non-metals
  • Only metals
  • Only noble gases
