  1. Off the top of your head, give an example for each of the four types of reactions: Displacement reaction Decomposition reaction Precipitation reaction Combination reaction Write balanced symbol equations for the examples you have given.

  2. About the assignment… • Authenticity Declaration • Resource list (e.g. web site addresses – must be specific) • Examples with balanced chemical equation • Due Friday week 7

  3. ASSESSMENT • March 14 Thursday – practical • March 15 Friday – practical • March 18 Monday – write-up • Bring your Exercise book & Clear file (Portfolio) on Thursday

  4. Question ONE Give the definitions of the four different types of chemical reactions

  5. Question TWO Predict what would happen if a piece of magnesium is left in a beaker of lead nitrate solution. Explain your answer.

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

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

  8. Question FIVE Predict what would happen if very finely ground aluminiumpowder is burnt using a blue Bunsen flame. Write down the balanced symbol equation.

  9. Question SIX Write down the word equation and the balanced symbol equation “When the mixture of iron filings and sulfur powder was heated, it reacted and iron sulfide compound was produced”

  10. Question SEVEN Write down the word equation and the balanced symbol equation “When calcium chloride solution and sodium carbonate solution were mixed together, white, cloudy substance was produced”

  11. 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”

  12. 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”
