When iron is heated with lead oxide, iron oxide and a shiny ball of lead are formed. From this we can deduce that ...

• lead is less reactive than iron

• iron is more reactive than oxygen

• iron is less reactive than lead

• lead is more reactive than iron

This metal (X) displaces copper from copper sulphate solution but does not displace zinc from zinc sulphate. From this we can tell that the order of reactivity (most reactive first) is

• zinc; copper; X

• zinc; X ; copper

• copper ; X ; zinc

• X; zinc;copper;
