=Decomposition=

In a decomposition reaction, a complex substance breaks down into its more simpler parts, one reactant forms two or more products.

The general equation is: **AB → A + B**

__An example could be__:
 * water decomposes to produce dihydrogen and dioxide

__Steps to changing the chemical sentence into an equation:__ 1.) Change the symbol into chemical name Water= H2O Hydrogen= H Oxygen= O 2.) Figure out the charge of each element( Since this is a covalent equation the written sentence already does the work for you so now all you have to do is read the sentence equation and do what it tells you: Di mean 2) H2O **→** H 2 + O2
 * 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, both oxygen and hydrogen are them.

__Balance the Equation:__ 1.) Under the equation make a table and count the amount of atoms in each type. H2O **→** H 2 + O2 2 H 2 1 O 2 2.) Since this equation is not balanced you have to change the coefficients, and //ONLY// the coefficients. 2H2O **→** 2H 2 + O2 4 H 4 2 O 2 3.) The equation is now balanced!
