Question

Explain displacement reaction?​

Answer 1

Answer:

Displacement reactions occur when a metal from the electrochemical series is mixed with the ions of a metal lower down in the electrochemical series. The atoms of the more reactive metal push their electrons on to ions of the less reactive metal

Answer 2

Answer:
