1. Double The Excitement

2.  Either a homogeneous mixture will occur  Or a Double Replacement chemical reaction will occur  Double Replacement Reactions: An exchange of positive ions between two compounds

3. Examples: AB+CD – AD+CB AE+TG – AG+TE

5.  Marble is eroded by acid rain through a double replacement chemical reaction

6.  Antacids that neutralizes stomach acids does this through a double replacement chemical reaction  For more fun facts go herehere

7. AB + XY  AY + XB 1) The outside portions (cation A and anion Y) combine to make a formula called AY. 2) the inside portions (anion B and cation X) switch so X (positive charge) and B (negative charge) goes secind to make a formula called XB.
