Combustion+P+GRady


 * Definition:** A substance rapidly combines with oxygen or hydrogen to produce one or more oxides.


 * Generic Formula:** A + O2 > CO2 + H2O

An example sentence of this is Carbon tetrahydrogen and oxygen are **heated** to form carbon dioxide and water. Heated is a key word there because when you see the word HEATED then that usually relates to combustion. To put this into equation form, the beginning would be **CaH4+O** but because **O** is alone again and diatomic it is written as **O2**. The equation put together would look like **CH4+O2--->CO2+H2O** Then to balance it, you have to add a 2 in front of the H2O on the right side of the arrow. **CH4+O2--->CO2+2H2O**
 * CH4+O2--->.** Next, Carbon dioxide is CO2 and water is H2O. This would be written to the left of the arrow.**--->CO2+H2O**
