Write down the oxidation and displacement reaction with statement

Dear Student,

Displacement reactions are those reactions in which an element replaces another element from its compound. Displacement reactions are basically of two types 

1) Single displacement reactions

2) Double displacement reaction

Single 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

For example:
Zinc + Copper sulphate -> Zinc sulphate + Copper
Zn _(s) + CuSO_{4 (aq)}  ->  ZnSO_{4 (aq)} + Cu _(s)

A Double Displacement Reaction 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

For example:
Pb(NO_{​​​​​3}​)₂ + 2KI -> PbI_{​​​​2} + 2KNO₃

 
P.S. For the remaining part of the question, kindly post it in a separate thread.
