What else is produced when a metal reacts with water? (HINT: Water has the formula H₂O)

• Metal Oxide
• Metal Carbonate
• Metal Hydride
• Metal Hydroxide

What gas is always produced when a metal reacts with water?

• Oxygen
• Carbon Dioxide
• Hydrogen
• Carbon Monoxide

When a metal salt reacts with a more reactive salt, what sort of reaction occurs?

• Displacement
• Neutralisation
• Combustion
• No Reaction

When magnesium reacts with copper sulphate, there are two products. What are they?

• Magnesium  and Copper
• Magnesium Sulphate and Copper
• Magnesium Sulphate and Copper Sulphate
• Magnesium and Copper Sulphate

When copper and magnesium sulphate are mixed together, there is no reaction. Why?

• Magnesium is more reactive than copper
• Copper is more reactive than magnesium
• Copper never reacts with metal salts
• Magnesium Sulphate never reacts with metals

What is the correct equation when potassium reacts with water?

• 2K (s) + H₂O (l) -->  KOH (aq) + H₂ (g)
• K (s) + 2H₂O (l) -->  KOH (aq) + 2H₂ (g)
• 2K (s) + 2H₂O (l) -->  2KOH (aq) + H₂ (g)
• K (s) + H₂O (l) -->  KOH (aq) + H₂ (g)
