video

KEY CONCEPTS:
-these reactions involve burning a hydrocarbon in the presence of oxygen. Hydrocarbons are compounds made by ONLY H and C atoms.

2 Types of Combustion Reactions:
i.) Complete Combustion (plenty of oxygen)
ii.) Incomplete Combustion (poor supply of oxygen)

Formulas for Combustion Reactions:

i.) Complete Combustion

C#H# + O2 --> CO2 + H2O

ii.) Incomplete Combustion Reactions:

C#H# + O2 --> CO2 + H2O + CO + C

**notice the difference in the Incomplete Combustion reactions
