 * //Single Displacement//**

Single displacement is a reaction in which a free atom becomes an ion and an ion becomes a free element. This can be represented by: A+BC->AC+B

An equation of single displacement is magnesium and hydrochloric acid forms magnesium chloride and hydrogen. In order to write this first write the symbols that represent the element. Then add the charges. Then do the switcheroo and reduce.

The formula for this is: Mg+2HCL>MgCl2+H2 This equation is balanced because it has the same number of atoms of the element on the reactant side as it does on the product side.
