Question

what is the difference between displacement and double displacement reactions write equation for these reactions which of these is a Redox reaction

Answer 1

displacement reactions are those in which an uncombined single element simply replaces the other in a compound. A general chemical equation for reaction is   

AB + X → AX + B


A Double Displacement Reaction on the other hand is a reaction involving two molecules in which parts of two compounds are exchanged to give two new compounds. The general equation used to represent double displacement reactions can be written as:

     AB + CD → AD + BC

Thus, single displacement reaction is the reaction between an element and a compound, while a double displacement reaction is the reaction between two compounds. Also, a single displacement reaction leads to the formation of a new compound and deposition of a new element, while a double decomposition reaction leads to the formation of two new compounds. 



example of redox reaction
H2S + Cl2 → 2HCl + S​
Cu+AgNO3  → 2Ag + Cu(NO3)2

☺ Hello mate__ ❤

◾◾here is your answer...

✒DEFINITION OF DISPLACEMENT REACTION::--

In a displacement reaction, a more reactive element replaces a less reactive element from a compound.

i.e. A + BX. -----> AX + B

where A is more reactive than B

Example :-

CuSO4 + Zn --> ZnSO4 + Cu

✒DEFINITION OF DISPLACEMENT REACTION::--

In a double displacement reaction, two atoms or a group of atoms change places to form new compounds.

i.e. AB + CD ---> AC + BD

Example:--

Na2SO4 + BaCl ---> NaSO4 + 2NaCl
