__Double+Displacement__

Double Displacement
A Double Displacement reaction is when 2 compounds exchange bonds to form different compounds.

The generic form of this reaction: AB+CD--->AD+CB

An example of this reaction is when Sodium Chloride and Silver Nitrate react and produce Sodium Nitrate and Silver Chloride. Now we have to make this sentence and equation: Sodium Chloride=NaCl Silver Nitrate=AgNO3 First half of the equation is NaCl+AgNO3--->? Now for the second half: Sodium Nitrate= NaNO3 Sliver chloride=AgCl Second half: NaNO3+AgCl Now put together the first and second part of the equation: NaCl+AgNO3--->NaNO3+AgCl Wait! What about balancing? Actually this equation is already perfectly balanced:)

Here is a picture of a Double Displacement reaction: This reaction creates a precipitate which is one of the substances separating from the others.
