1. Saturated hydrocarbons are called alkanes
2. Small chain hydrocarbons are used as fuels
3. The reaction is called combustion
4. The word equation for this chemical reaction is :
fuel (hydrocarbon) + oxygen → carbon dioxide + water + ENERGY (heat, light, sound)
5. If there is insufficient oxygen then the word equation is:
fuel (hydrocarbon) + oxygen → carbon monoxide + water + ENERGY (heat, light, sound)
6. The problem with this reaction is that carbon monoxide is produced this gas is a dangerous to the human body (see objective 5.11)
7. Where can you find incomplete combustion? Cars
8. What is used to reduce the harmful products from incomplete combustion? Catalytic Converter
9. During incomplete combustion a smoky flame is often seen, explain this observation
Grey Clouds of Gases & Nasty Smell
Extn: write a balanced equation (with state symbols) for the combustion of propane gas
C3H8 + 5O2 --> 3CO2 + 4H2O
