What happens in a displacement reaction?

A more reactive element displaces (pushes out) a less reactive element.

What is produced when iron reacts with copper sulfate?

Iron sulfate + copper.

What is the symbol equation for iron reacting with copper sulfate?

Fe + CuSO₄ → FeSO₄ + Cu.

What condition is needed for a displacement reaction to take place?

The element on its own must be more reactive than the element in the compound.

Why does iron displace copper in copper sulfate?

Iron is more reactive than copper.

What is produced when lead reacts with copper sulfate?

Lead sulfate + copper.

What is the symbol equation for lead reacting with copper sulfate?

Pb + CuSO₄ → PbSO₄ + Cu.

Will iron react with magnesium sulfate? Why?

No, because iron is less reactive than magnesium (cannot displace magnesium).

Will lead displace iron from iron sulfate?

No, because lead is less reactive than iron.

Will zinc displace silver from silver nitrate?

Yes, because zinc is more reactive than silver. (Products: zinc nitrate + silver)

Will zinc displace iron from iron oxide?

Yes, because zinc is more reactive than iron. (Products: zinc oxide + iron)

Will iron displace copper from copper oxide?

Yes, because iron is more reactive than copper. (Products: iron oxide + copper)
