Question

what is displacement reaction​

Answer 1

Answer:

A single-displacement reaction, also known as single replacement reaction or exchange reaction, is a chemical reaction in which one element is replaced by another in a compound.

Answer 2

• Displacement reaction:
• A displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule. For example, iron is added to a copper sulphate solution, it displaces the copper metal.
• It is also known as substitution reaction or metathesis reaction .
• Types:

            Single displacement reaction  

            Double displacement reaction.

• Single displacement reaction:

                 A single displacement reaction is a chemical reaction in which one element is substituted for another element in a compound, generating a new elements and a new compound as products.

                    eg...2HCl(aq)+Zn(s)→ZnCl2(aq)+H2(G)

• Double displacement reaction:

               A double displacement reaction is as type of chemical reaction where two compounds react, and positive ions and negative ions of the two reactants, forming two new compounds or products.

                   eg...Na2S+2HCl→2NaCl+H2S
