Reactivity series

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

In order to make use of the many useful properties of metals, we need to extract them so that they are in their pure form. A common way of extracting many of the less reactive metals is to heat their minerals with what?

• Carbon
• Helium
• Oxygen
• Silicon
