Double+Displacent+Reaction+Shooshanian

=DOUBLE DISPLACEMENT REACTION: Shooshanian=

A double displacement reaction is when the two elements replace two other elements. The generic form of this is:
 * AB+CD--->AD+CB**

An example of this is a sentence is: Silver nitrate reacts with sodium chloride to form silver chloride and sodium nitrate.

To make this into an equation, you have to know that //nitrate// is polyatomic. That means, to write it, it should be (NO3).

Next you add the charges. Ag1(NO3)-1+Na1Cl-1 since they are all 1's, the first half of the equation remains the same.
 * Ag (NO3) + NaCl**

For the second half, you have The charges here also stay the same since they are the same elements as the first half and all have a charge of 1 or -1. The equation is already even on both sides so you don't have to balance it but you can check it. __1__ Ag __1__ __3__ NO __3__ __1__ Na __1__ __1__ Cl __1__
 * AgCl+Na(NO3)**
 * Ag(NO3)+NaCl--->AgCl+Na(NO3)**
