Synthesis : It is a type of chemical reaction in which two or more than two reactants combines together to form a single product.
[tex]A+B+2C\rightarrow ABC_2[/tex]
Where as sublimation and deposition are process related to the change in state of the matter.
Sublimation: Conversion of substance from solid state to gaseous state directly.
Deposition:Conversion of substance from gaseous state to solid state directly.
