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
