2 Na + Cl -

3 Mg ++ Cl -

4 Na + SO 4 --

5 Mg ++ SO 4 --

6 Using the materials provided construct the following: Sodium Chloride Sodium hydroxide Magnesium Chloride Calcium hydroxide Aluminium chlorideSodium oxide Sodium carbonateSulfuric acid Hydrochloric acidAluminium oxide

7 Balancing Chemical Equations Balance the following equations using the materials provided: Sodium hydroxide + Hydrochloric acid → Sodium chloride + Water Magnesium hydroxide +Hydrochloric acid → Magnesium chloride + Water

8 H+H+ Na + Cl - OH - +

9 Na + H+H+ Cl - OH - +

10 HCl + NaOH→NaCl +H₂O

11 Mg ++ OH - H+H+ Cl - +

12 Mg ++ OH - H+H+ Cl - + H+H+ +

13 Mg ++ Cl O -- H+H+ H+H+ H+H+ H+H+

14 Mg(OH)₂ + 2HCl→MgCl₂ +2H₂O

15 Balance the following equations without using the materials provided: Zinc + Hydrochloric Acid→ Zinc Chloride + Hydrogen Hydrogen Peroxide → Oxygen + Water Sodium Hydroxide + Hydrochloric Acid → Sodium Chloride +Water

16 Balance the following equations without using the materials provided: Zinc + Hydrochloric Acid → Zinc Chloride + Hydrogen Zn + 2HCl → ZnCl₂ + H₂ Hydrogen Peroxide → Oxygen + Water 2H₂O₂ → O₂ + 2H₂0 Sodium Hydroxide + Hydrochloric Acid → Sodium Chloride +Water NaOH + HCl → NaCl + H₂o

17 Calcium Carbonate + Hydrochloric Acid → Calcium Chloride + Carbon Dioxide +Water Sodium + Oxygen → Sodium Oxide Calcium Carbonate + Sulfuric Acid → Calcium Sulfate + Carbon Dioxide Water

18 Calcium Carbonate + Hydrochloric Acid → Calcium Chloride + Carbon Dioxide +Water CaC0₃ + 2HCl → CaCl₂ + CO₂ + H₂O Sodium + Oxygen → Sodium Oxide 4Na + O₂ → 2Na₂O Calcium Carbonate + Sulfuric Acid → Calcium Sulfate + Carbon Dioxide Water CaC0₃ + H₂SO₄ → CaSO₄ + CO₂ + H₂O

19 Sodium + Sulfuric Acid → Sodium Sulfate + Hydogen Magnesium + Sulfuric Acid →Magnesium Sulfate +Hydrogen Potassium + Water → Potassium Hydroxide + Hydrogen

20 Sodium + Sulfuric Acid → Sodium Sulfate + Hydogen 2Na + H₂SO₄ → Na₂SO₄ + H₂ Magnesium + Sulfuric Acid →Magnesium Sulfate +Hydrogen Mg + H₂SO₄ → MgSO₄ + H₂ Potassium + Water → Potassium Hydroxide + Hydrogen 2K + 2H₂O → 2KOH + H₂
