3.4 I can recall the products of the complete and incomplete combustion of alkanes

Saturated hydrocarbons are called alkanes.
Small chain molecules are used as fuels.
The reaction is called combustion.
The word equation for this chemical reaction is
fuel + oxygen -> carbon dioxide + water + energy (heat, light, sound)
If there is insufficient oxygen then the word equation is:
fuel +inefficient oxygen -> water + carbon monoxide + energy (heat,light,sound)
The problem with this reaction is that carbon monoxide is produced this gas is a poison to the human body.
Where can you find incomplete combustion?
You can find incomplete combustion in car engines.
What is used to reduce the harmful products from incomplete combustion?

During incomplete combustion a smoky flame is often seen, explain this observation.

Describe the chemical test for carbon dioxide gas?
Limewater turns milky.
Describe a physical test for water?
Heating water in a beaker, and it's boiling point will be 100 degrees.

3.2 & 3.3 Recall that alkanes have the general formula CnH2n+2/draw displayed formula for alkanes with up to five carbon atoms in a molecule, and name the straight-chain isomers

1. First Five Alkanes:

2. What is the general formula for alkanes?
CnH2n+2
3. Describe and explain the trend in boiling point.
As the number of carbons increases the boiling point also increases.

3.1 Explain the terms homologous series, hydrocarbons, saturated, unsaturated, general formula and isomerism

Definitions:
Homologous series-
Is an alkane family of organic compounds.
Hydrocarbon-
Contain hydrogen and carbon only.
Saturated hydrocarbon-
Compounds with single bonds.
Unsaturated hydrocarbon-
Compounds with multiple bonds between carbon atoms
General formula-
CnH(2n+2)
Isomerism-
Are compounds with different display formula and same molecular formula.
