Double+Displacement.bertino

=__Double-Displacement__=

This is when the anions and cations of two different molecules switch places, forming two entirely different compounds. Or in simpler words the metals are switching spots.

The general equation is: **AB + XY → AY + XB**

__An example could be__:
 * Potassium Iodide and lead nitrate react to produce lead iodide and potassium nitrate

__Steps in changing the chemical sentence to a formula:__ 1.) Change the chemical names into their symbols Potassium = K Iodine= I Lead = Pb Nitrate= NO3 2.) Figure out the charge of each element Potassium +1 Iodine -1 Lead +2 Nitrate -1 3.) Do the Switcheroo KI+ Pb(NO3)2 → PbI2 + K(NO3) 4.) Reduce if possible

__Balance the Equation:__ 1.) Under the equation make a table and count the amount of atoms in each type. KI+ Pb(NO3)2 → PbI2 + K(NO3) 1 K 1 1 Pb 1 1 I 2 2 (NO3) 1 2.) Since this equation is not balanced you have to change the coefficients. 2KI+ Pb(NO3)2 → PbI2 + 2K(NO3) 2 K 2 1 Pb 1 2 I 2 2 (NO3) 2 3.) The equation is now balanced!
