synthesiss

Synthesis: Is a type of reaction when two compounds or elements combine to make one molecule or compound.

Generic Form: **A+B--->AB**

Iron and oxygen combine to form magnesium oxide. To make this into and equation, you need to identify the symbols for iron and oxygen. Iron is Fe and Oxygen is O. Fe+O If Oxygen is alone it becomes O2 because it is diatomic. To find the product, you combine the elements together: Mg+O2--->MgO**
 * Fe+O2**
 * FeO2

Next you have to balance the equation. __1__ Fe __1__ __2__ O __1__ Since there are more oxygens on one side, place a 2 in front of the Fe on the right side of the equation. Fe+O2--->2FeO But now we also have to place a 2 in front of the Fe on the left side of the equation to have Fe2 on both sides. This gives us our final result.
 * 2Fe+O2--->2FeO**
