1. Which of the following metals is in the correct order of decreasing reactivity?
- A. Potassium, sodium, calcium, magnesium
- B. Magnesium, calcium, sodium, potassium
- C. Sodium, potassium, magnesium, calcium
- D. Calcium, magnesium, potassium, sodium
2. What is the product when sodium reacts with cold water?
- A. Sodium oxide and hydrogen gas
- B. Sodium hydroxide and hydrogen gas
- C. Sodium carbonate and water
- D. Sodium chloride and oxygen gas
3. Why does magnesium react with steam but not with cold water at room temperature?
- A. Magnesium is insoluble in cold water
- B. The higher temperature of steam provides more energy for the reaction to occur
- C. Cold water contains dissolved oxygen which prevents the reaction
- D. Magnesium forms a layer of magnesium carbonate in cold water
4. A student carries out displacement reactions with four metals and copper sulphate solution. Metal X causes a displacement reaction, but metals Y and Z do not. Which statement must be true?
- A. Metal X is less reactive than copper
- B. Metal X is more reactive than copper, but metals Y and Z are less reactive than copper
- C. All three metals are more reactive than copper
- D. Copper is more reactive than all three metals
5. Aluminium is less reactive in air than would be expected from its position in the reactivity series. This is best explained by which of the following?
- A. Aluminium has a very low density which reduces its reactivity
- B. A thin, impermeable layer of aluminium oxide forms on the surface, protecting the metal beneath from further oxidation
- C. Aluminium is more electronegative than other reactive metals
- D. Aluminium exists naturally as aluminium oxide, so it cannot react further
