1. Combustion Reactions
Ties into: Periodic table, species, metals, nonmetals, metalloids(semi-metals), ionic and molecular, alkanes, carbohydrates

2. Combustion Definition
Reactions that occur in the presence of oxygen.

3. Generic Word Equation (w/elements)
Fuel + Oxygen -> fuel oxide(s)

4. Elements and combustion
Sodium (s) + Oxygen (g) -> Sodium oxide (s)
What do the (s) and (g) mean?
How do we determine them from the periodic table?
How do we know the (s) for Sodium oxide?
What is an ionic Compound?

5. More examples of combustion
Carbon (s) + Oxygen (g) -> carbon dioxide (g)
What do the (s) and (g) mean?
How do we determine them from the periodic table?
How do we know the (g) for carbon dioxide?
What is a molecular Compound?

6. Compounds and combustion
Octane (l) + oxygen (g) -> ?

7. Octane? Alkanes- hydrocarbons with single bonds.
Hydrocarbon meaning hydrogen and carbon
Examples:
Methane CH4 (g)
Ethane C2H6 (g)
Propane C3H8 (g)
Butane C4H10 (g)

8. Sooo… Generic example for combustion of compounds is…
Octane (l) + oxygen (g) -> ?
Generic example for combustion of compounds is…
FUEL + oxygen -> F oxides+ U oxides+ E oxides+ L oxides

9. Octane (l) + oxygen (g) -> Carbon dioxide (g)+ Water(g)
