A double replacement reaction is a chemical reaction between 2 compounds where the positive ion compound is exchanged with another.
Hope that helps you out, sorry if it doesn't but i have tried my best and that's all you could ask for from be because you don't even know who I am.

oh and sorry if there are spelling mistakes
During a double displacement reaction, the ions of two compounds switch places to form two new compounds.
An example would be... (The reaction is made up) NaSOU4+PoBNF2=>PoBOU4+NaSNF2 The NaS and the PoB switched places. reactant+compound+Reactant+compund=Product Compound+Product Compound
In a double replacement reaction a change of bonds between reactants occur.
