  1. Starter Question CuO + H2→ Cu + H2O What mass of copper metal would be obtained by the complete reduction of 15.9g of copper (II) oxide by hydrogen gas? 2. KOH + H2SO4 → K2SO4 + H2O 50cm3 of 0.4mol/l potassium hydroxide solution exactly neutralises 20cm3 of sulphuric acid. What concentration was the acid? 2. KOH + H2SO4 → K2SO4 + H2O 50cm3 of 0.4mol/l potassium hydroxide solution exactly neutralises 20cm3 of sulphuric acid. What concentration was the acid? You have 5 minutes after the final bell

  2. The Reactivity Series This is a list of metals (and non- metals) that places the metals in order of reactivity. The most reactive metals are at the top and the least reactive at the bottom We can use the reactivity series to predict whether or not a reaction will occur

  3. Chemical Bullies Rule ‘A metal higher in the activity series will displace a lower one out of solution’ e.g. Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s)

  4. Now predict whether the following reactions will occur. If they will try and predict the products of the reactions Assume all transition metals have a valancy of 2 Magnesium and zinc sulfate Sodium and water Tin and aluminum chloride Iron and copper sulfate Mg(s) + ZnSO4(aq) → MgSO4(aq) + Zn(s) Na(s) + H2O(l) → NaOH(aq) + H2(g) No reaction Fe + CuSO4→ FeSO4 + Cu

  5. Today’s Task Complete the worksheet. You have 40 minutes If you finish before the bell collect a copy of the white book and answer the questions on p 45

  6. Exit Ticket Answer the following questions then hand in. When you have completed both these tasks you may pack up 0.24 moles of a salt is dissolved to make 1.2l of solution. What is the concentration of the solution? Aqueous solutions of aluminum chloride and sodium hydroxide are mixed, forming the precipitate aluminum hydroxide. Write a balanced ionic equation for this reaction Predict if the following reaction will occur. If it does write a balanced equation for the reaction Cl2(g) + HF(aq) →
