__**Synthesis Reactions**__, aka Composition Reaction

--> When when two or more substances combine to form a new compound. A+ X --> AX

__Sentence Form of Reaction:__

Hydrogen Gas reacts with Oxygen Gas to form Water

__Conversion to Reaction:__

The process of converting the sentence into the reaction form of the chemical reaction is only successful if you use these following four steps for Ionic Nomenclature: 1) You must write the symbols that are used in the reaction. H + O --> H20

2) Second you have to find out what the charge of each element is: The charge of hydrogen is -1. The charge of Oxygen is +2.

Since this is a synthesis reaction, on the left side of the equation you do not need to do the next step but since each of the reactants are Diatomic Elements they each have 2 atoms.

3) The Third step that you have to do is to use the "Switcheroo Method". Which is where you take the charge of each atom and bring it down to the opposite element so that there is X amout of atoms for that Element. X simply being the charge of the opposite Element/ Compound. H2 + O2 --> H2O

__Balancing the Equation__:

4) The fourth and last step of the process is to Balance the equation. The idea of balancing is that you want to use coefficients to make the number of atoms for each element equal on each side of the equation. What you want to do is look at both sides of of the equation and figure out how many of each element or compound you will need to use. H2 + O2 --> H2O > Since there is Two Oxygen atoms on the left side of the equation you will need to use the coefficient 2 in front of the H2O compound in order to get The number of OXygens equal. H2 + O2 --> 2 H2O Since there was already two Hydrogen atoms on the right side of the equation, that makes the amount of atoms on the right side Four. So you will need to use the coefficient 2 in front of the H2 on the left side of the equation.


 * 2 H2 + O2 --> 2 H2O** > The final formula for the chemical reaction which has taken place.
