C4: Quiz 6 – Answers
1) Yes
2)
a) Yes (magnesium is more reactive than copper)
b)
i) magnesium + copper sulfate –> magnesium sulfate + copper
ii) Mg + CuSO4 -> MgSO4 + Cu
3) Yes, a reaction does take place because zinc is more reactive than iron, so zinc can displace iron in iron sulfate
Word equation:
zinc + iron sulfate –> zinc sulfate + iron
4) No, a reaction does not take place because copper is less reactive than magnesium (or magnesium is more reactive than copper). This means that copper cannot displace magnesium in magnesium sulfate
5) Yes, a reaction does take place because potassium is more reactive than calcium, so potassium can displace calcium in calcium chloride
Word equation:
potassium + calcium chloride –> potassium chloride + calcium
Questions
1) Will a more reactive metal displace a less reactive metal from its compound? Answer yes or no.
2)
a) Is magnesium more reactive than copper?
b) I add some magnesium to a copper sulfate solution.
i) Write the word equation for the reaction.
ii) Write the balanced chemical equation for this reaction.
3) A student adds zinc to an iron sulfate solution. Will a reaction take place? Explain why. If a reaction does take place, write the word equation.
4) A student adds copper to a magnesium sulfate solution. Will a reaction take place? Explain why. If a reaction does take place, write the word equation.
5) A student adds potassium to a calcium chloride solution. Will a reaction take place? Explain why. If a reaction does take place, write the word equation.
