Respuesta :
This is a double replacement because both Copper and Sodium reacted with each other compounds , hence "double"
The reaction represented when sodium chloride reacts with copper sulfate to produce sodium sulfate and copper chloride is a double replacement reaction.
Explanation
A double replacement reaction is type of chemical reaction where two compound react and a positive ions and negative ions of the two reactant switch places forming new compound.
The reaction of sodium chloride + Copper sulfate → sodium sulfate + copper chloride is a double replacement reaction because;
- sodium since it is a more reactive metal than copper it replaces copper from it's compound which result to formation of new products( sodium sulfate and copper chloride)
