• 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
