=__Single Displacement__=

In a single replacement reaction a single uncombined element replaces another in a compound. In the end the two reactants will yield two products.

The general equation is: **A+ BC → AC+ B**

__An example could be:__
 * Magnesium replaces hydrogen in water to make magnesium hydroxide and hydrogen gas

__Steps in changing the chemical sentence to a formula:__ 1. Change the chemical names into their symbols Magnesium = Mg Hydrogen = H Hydroxide = OH Oxygen = O 2. Figure out the charge of each element Magnesium +2 Hydrogen +1 Hydroxide -1 Oxygen +2 3. Do the Switcheroo Mg + H2O → Mg(OH)2 + H2 4. Reduce if possible
 * When writing a formula you must remember that there are some elements that are so reaction that they form molecules of twos when found alone. These elements are called diatomic elements and hydrogen is one of them.

__Balance the Equation:__ 1.) Under the equation make a table and count the amount of atoms in each type. Mg + H2 O → H2 + Mg(OH)2 1 Mg 1 2 H 4 1 O 2 2.) Since this equation is not balanced you have to change the coefficients and //ONLY// the coefficients. Mg + 2H2 O → H2 + Mg(OH)2 1 Mg 1 4 H 4 2 O 2 3.) The equation is now balanced!
