Q6:
Which of the following best describes a displacement reaction?
- AA reaction where a molecule is broken down into smaller molecules or its elemental components
- BA reaction where a reactive element combines with a less reactive element to form a new compound
- CA reaction where two soluble metal salts react to form an insoluble salt
- DA reaction where a more reactive element replaces a less reactive element from a compound
- EA reaction between ionic species in aqueous solution
Q7:
In an experiment, four beakers were filled with an aqueous copper nitrate solution. A thermometer was placed into each beaker and the temperature of the solution was measured. A piece of metal was then dropped into each beaker, as shown in the diagram. Any changes in temperature were then observed and recorded.
In which beaker would the largest change in temperature be observed?
- A(B)
- B(D)
- C(B) and (C)
- D(C)
- E(A)
In which beaker would no change in temperature be observed?
- A(B)
- B(D)
- C(D) and (C)
- D(A)
- E(C)
Q8:
Based on the positions of the metals in the reactivity series, it is possible to predict whether a reaction would or would not occur between certain pairs of chemicals if the two were mixed together.
Based on the positions of the metals in the reactivity series, would a reaction occur between and if the two were mixed together?
- AYes
- BNo

- AYes
- BNo
Q9:
In an experiment, a beaker is filled with a blue copper(II) sulfate solution. A piece of magnesium ribbon is then dropped—completely submerged—in the solution. What observations would you expect to see?
- AThe solution would change from blue to orange, and the magnesium would turn blue.
- BA blue gas would be produced, and effervescence would occur.
- CThe solution would change from blue to colorless, and there would be no solid present in the beaker.
- DThe solution would remain blue, and there would be no change to the magnesium ribbon.
- EThe solution would change from blue to colorless, and the ribbon would become coated with copper.
