Combustion Substance (usually a fuel w/ C & H) + oxygen

oxides, light, heat

Fuel + O2

CO2 + H2O

CH3OH + O2 CO2 + H2O

•compound made only of hydrogen and carbon

• HxCy + O2 CO2 + H2O

• Example

CH4 + 2 O2 CO2 + 2 H2O

• HxCyOz + O2 CO2 + H2O

• Example

C2H4O2 + 2 O2 2 CO2 + 2 H2O

• If H2CO3 is formed, it immediately decomposes into H2O and CO2

• If H2SO3 is formed, it immediately decomposes into H2O and SO2
