displacement reactions of metals

• What are two properties of group 1 metals?

  Soft and highly reactive
• What are two properties of transition metals?

  Good conductors and high melting points
• Write the word equation for lithium and water.

  Lithium + Water → Lithium hydroxide + Hydrogen
• Write the word equation for iron(III) oxide and carbon.

  Iron(III) oxide + Carbon → Iron + Carbon dioxide
• Write the word equation for magnesium and hydrochloric acid.

  Magnesium + Hydrochloric acid → Magnesium chloride + Hydrogen
• What happens when iron metal is added to copper sulphate solution?

  Iron displaces copper from the solution
• Why does iron displace copper in the reaction with copper sulphate?

  Iron is more reactive than copper
• What is a displacement reaction?

  A reaction where one metal displaces another
• Complete the equation: Magnesium + iron chloride → ?

  Magnesium chloride + Iron
• How can the reactivity series be used in predicting reactions?

  It ranks metals by their reactivity
• Write the word equation for copper(II) chloride and zinc.

  Copper(II) chloride + Zinc → Copper + Zinc chloride
• Write the word equation for copper placed in silver nitrate solution.

  Copper + Silver nitrate → Silver + Copper nitrate
• Write the balanced symbol equation for copper nitrate and magnesium.

  Cu(NO₃)₂ + Mg → Mg(NO₃)₂ + Cu
• Write the balanced symbol equation for aluminium sulphate and calcium.

  Al₂(SO₄)₃ + 3Ca → 3CaSO₄ + 2Al
• Write the balanced symbol equation for copper chloride and aluminium.

  3CuCl₂ + 2Al → 2AlCl₃ + 3Cu
• Why are metals cleaned before reactions?

  • To remove oxide layers
  • To ensure accurate results
  • To enhance reactivity
• Why is zinc used to coat cars before painting?

  • Prevents rusting
  • Acts as a sacrificial metal
  • Protects underlying metal
• Why is jewellery made from gold, silver, and platinum?

  • They are non-reactive
  • They resist tarnishing
  • They are durable and attractive
• What would happen if gold is placed in copper sulphate?

  No reaction occurs
• Write the word equation for magnesium and zinc chloride.

  Magnesium + Zinc chloride → Zinc + Magnesium chloride
• Write the word equation for silver and copper sulphate.

  Silver + Copper sulphate → No reaction
• Write the word equation for zinc and iron chloride.

  Zinc + Iron chloride → Iron + Zinc chloride
• What are the steps to write balanced equations?

  1. Write the unbalanced equation
  2. Count atoms of each element
  3. Adjust coefficients to balance
  4. Ensure mass is conserved
• What are the key features of displacement reactions?

  • One metal displaces another
  • Reactivity series determines outcomes
  • Often produce visible changes
