Reaction+Quatro-+Double+Displacement


 * DOUBLE DISPLACEMENT:**

Double displacement is similar to single displacement in the sense that two of the elements in the equation switch positions during the reaction. However in double displacement, there are two compounds on each side of the equation, rather than a single element and a compound.

Generically, a double displacement equation looks like this: AB + CD  à CB + AD

An actual equation could be: Silver Nitrate and Sodium Chloride react to form Sodium Nitrate and Silver Chloride In order to change this into a formula, you must first know the symbols for each element in the equation Silver=Ag Nitrate= NO 3 Sodium=Na Chlorine= Cl The word “and” (sometimes replaced with “plus”) always refers to a + sign. Any form of “creates” “makes” “forms” etc. will indicate an arrow (  à ). So far we know: AgNO 3 + NaCl  à NaNO 3 + AgCl OH NO! Just like the single displacement example I gave, the equation that was just given is actually already balanced. There is 1 silver, sodium, nitrate, and chlorine on each side of the equation. If you are still confused as to how to balance, you can always look over my Synthesis and Decomposition pages again, or hold your horses and wait until you rerd the combustion page, as that will have some balancing to do. The final equation stands: …and everyone is happy.  J   Click to go Back to Main Page
