  1. Question ONE Using examples, describe the relationship between: Decomposition reaction and Combination reaction Precipitation reaction and displacement reaction

  2. Question TWO Predict what would happen if a piece of aluminiumis left in a beaker of coppernitrate solution. Explain your answer.

  3. Question THREE Predict what would happen if sodium sulfate solution and barium nitrate are mixed together. Explain your answer.

  4. Question FOUR Predict what would happen if sodium carbonate powder is strongly heated in a crucible over a blue Bunsen flame. Write down the balanced symbol equation.

  5. Question FIVE Predict what would happen if copper metalpowder is burnt using a blue Bunsen flame. Write down the balanced symbol equation.

  6. Question SIX Write down the word equation and the balanced symbol equation “When the mixture of zincfilings and sulfur powder was heated, it reacted and zincsulfide compound was produced”

  7. Question SEVEN Write down the word equation and the balanced symbol equation “When aluminiumchloride solution and potassium hydroxide solution were mixed together, white, cloudy substance was produced”

  8. Question EIGHT Write down the word equation and the balanced symbol equation “When mercury oxide solution (HgO) was strongly heated, mercury metal (Hg) and oxygen gas were produced”

  9. Question NINE Write down the word equation and the balanced symbol equation “When a piece of aluminium was dropped into blue, transparent copper nitrate solution, the solution turned colourless and brown solid was produced”
