Question

Giving one example of each, differentiate between a displacement reaction and a double displacement reaction.

Answer 1

Displacement reaction	Double displacement reaction
The displacement reaction occurs when a more reactive element removes a less reactive element from a solution.	A double displacement reaction occurs when the ions of both reactants exchange places to generate new molecules.
Example: \[\ce{CuSO4_{(aq)} + Fe_{(s)} -> FeSO4_{(aq)} +Cu_{(s)}}\]	Example: \[\ce{AgNO3_{(aq)} + NaBr_{(aq)} -> NaNO3_{(aq)} + AgBr_{(s)}}\]
