What type of reaction is

2A1Br3 + 3K2SO4+6KBr +

Al2 (SO4) 3

Synthesis/Combination

Decomposition

Single Replacement

Double Displacement

or Combustion?

Answer: Double Displacement

Explanation: In a double displacement reaction it is shown through this generic description

AB + CD = > AD + CB

Where A and C are both metals and B and D are nonmetals.

A is Al

B is Br

C is K

D is SO4

In this reaction

Al displaces K to combine with SO4

K combines with Br forming KBr
