  1. Question 1

    Reactivity series (most reactive first): potassium, sodium, calcium, magnesium, aluminium (aluminum), zinc, iron, copper, silver, gold. If zinc is added to a solution of aluminium (aluminum) sulfate, will a displacement reaction happen?

    • A. yes
    • B. no

  2. Question 2

    Iron is extracted from iron oxide by heating it with carbon. Why does this work?

    • A. Carbon is more reactive than iron, so it removes the oxygen
    • B. Iron is more reactive than carbon
    • C. Heat alone splits iron oxide
    • D. Carbon is a metal

  3. Question 3

    Reactivity series (most reactive first): potassium, sodium, calcium, magnesium, aluminium (aluminum), zinc, iron, copper, silver, gold. If silver is added to a solution of copper sulfate, will a displacement reaction happen?

    • A. yes
    • B. no

  4. Question 4

    Iron is extracted from iron oxide by heating it with carbon. Why does this work?

    • A. Carbon is more reactive than iron, so it removes the oxygen
    • B. Iron is more reactive than carbon
    • C. Heat alone splits iron oxide
    • D. Carbon is a metal

  5. Question 5

    Reactivity series (most reactive first): potassium, sodium, calcium, magnesium, aluminium (aluminum), zinc, iron, copper, silver, gold. If aluminium (aluminum) is added to a solution of iron sulfate, will a displacement reaction happen?

    • A. yes
    • B. no

  6. Question 6

    Iron is extracted from iron oxide by heating it with carbon. Why does this work?

    • A. Carbon is more reactive than iron, so it removes the oxygen

  7. Question 7

    Reactivity series (most reactive first): potassium, sodium, calcium, magnesium, aluminium (aluminum), zinc, iron, copper, silver, gold. If aluminium (aluminum) is added to a solution of silver sulfate, will a displacement reaction happen?

    • A. yes
    • B. no

  8. Question 8

    What does "oxidation" mean in terms of oxygen?

    • A. gain of hydrogen
    • B. loss of oxygen
    • C. melting
    • D. gain of oxygen

  9. Question 9

    Reactivity series (most reactive first): potassium, sodium, calcium, magnesium, aluminium (aluminum), zinc, iron, copper, silver, gold. If calcium is added to a solution of magnesium sulfate, will a displacement reaction happen?

    • A. yes
    • B. no

  10. Question 10

    Why is gold found as the pure metal in the ground?

    • A. It is very unreactive
    • B. It is magnetic
    • C. It is a non-metal
