Combustion Reactions
H2 + O2 H2O22
C + O2 CO2
Combustion of Ethane (C2H6)
Complete combustion…
Only two products in the complete combustionof a hydrocarbon.
C2H6 + O2 CO2 + H2O6472
Incomplete Combustion
C24H50 + 26O2 → 5C + 8CO2
+ 25H2O + 11CO
Four products result in the incomplete combustionof a hydrocarbon.
