Metal displacement reactions

Question 1

4 types of chemical reactions

Answer 1

• synthesis
• decomposition
• single displacement
• double displacement

Question 2

What is single displacement

Answer 2

• A + BC → AC + B
• Characterised by one element being displaced from a compound by another element

Question 3

What is double displacement?

Answer 3

• AB + CD → AD + CB
• characterised by the change in position of both metals
• eg, precipitation, neutralisation

Question 4

Metal displacement reactions

Answer 4

• metals only replace metals, non metals only replace non metals
• The activity series of metals determines which metals will displace other metals
• In the activity series, the element higher on the list (more reactive) will replace a compound lower on the list (less reactive)
