=__Double Displacement__=

A Double Displacement reaction is similar to the single displacement reaction except in this reaction, two compounds are reacting. In the end, one element from the first compound is in the second compound and one element from the second compound is in the first.

AB + CD → AD + CB

Calcium Chloride and Silver Nitrate react to form Calcium Nitrate and Silver Chloride.

CaCl2 + 2Ag(NO3) → Ca(NO3)2 + 2AgCl

When the equation is first written, it should look like this: CaCl + Ag(NO3) → Ca(NO3) + AgCl. Calcium's charge is +2 so both chloride on the left and silver on the right should be multiplied by two. Next to match their other-side counterparts, they should also be multiplied by two on the opposite side. This finishes it up.
