Displacement reactions

The starting materials in a chemical reaction are known as...

• Products

• Reactants

• Starters

• Enders

Answer explanation

Reactants react together.

A substance that is formed as the result of a chemical reaction

• Product 

• Reactant

• Starters

• Enders

Answer explanation

Products are produced.

A displacement reaction will occur when...

• A more reactive metal displaces a less reactive metal from its compound.

• A less reactive metal displaces a more reactive metal from its compound

What will the products of this reaction be?

calcium + zinc nitrate --------->

• Zinc + calcium nitrate

• there will be no reaction

• Zinc + calcium chloride

Select the keyword that matches the description below.

"A reaction involving a more reactive metal removing a less reactive metal from its compound"

• Displacement

• Reduction

• neutralisation

Reaction or no reaction?

Lead + iron sulphate ==>

• Reaction

• No reaction

Answer explanation

Lead can't displace iron from iron sulphate because lead is LESS reactive than iron

Reaction or no reaction?

Zinc + copper sulphate ==>

• Reaction

• No reaction

Answer explanation

Zinc is MORE reactive than copper, therefore zinc will displace copper from copper sulphate

Reaction or no reaction?

Copper + copper sulphate ==>

• Reaction

• No reaction

Answer explanation

Copper can't displace itself from a compound because copper atoms are all the same (there is no difference in reactivity)
