Reaction+Two+Decomposition


 * __Decomposition Reaction__**

--> When a single compound undergoes a reaction that produces two or more simpler substances. AX --> A+X

__Sentence Form of Reaction:__

Water breaks down to form Hydrogen gas and Oxygen gas.

__Conversion to Reaction:__ (Following the steps from the First reaction)

1) H2O --> H2 + O2 ; The symbols of each element/compound are written.

2) The charges of each Element are the same as the last equation that i used. Hydrogen= +1, Oxygen -2.

3) The "Switcheroo Method" has already been put into use where it was needed to be used.

The Hydrogen in water has two atoms because the -2 charge of Oxygen made it so.

H20 --> H2 + O2

__Balancing the Equation:__

4) The Balancing of the Equation again comes from the fact that each side of the equation has to have an equal amount of Atoms for each Element/ Compound. The amount of H is already equal at this point, but the O on the right side of the equation has 2 atoms, unlike the opposite sides O which only has 1. So you need to place the coefficient 2 in front of the H2O on the left side of the equation. 2 H2O --> H2 + O2 From that coefficent 2, you now have 4 atoms of H on the left side so you'll need to go back to the right side of the equation so that each side will have 4 atoms of H. 2 H2O --> 2 H2 + O2


 * 2 H20 --> 2 H2 + O2** > Becomes the final formula for this Decomposition Reaction.
