*** WHAT’S COVERED ***
1. Properties of alkanes and how they change with carbon chain length.
* The trend in boiling points.
* State at room temperature (gas, liquid, solid).
* Volatility, viscosity, and flammability.
2. The complete combustion of alkanes.
* The reactants (hydrocarbon and oxygen) and products (carbon dioxide and water).
* Explanation of combustion as an exothermic oxidation reaction.
3. How to write and balance chemical equations for complete combustion.
* A step-by-step worked example for the combustion of propane.
* A step-by-step worked example for the combustion of nonane.
