1. Redox and Combustion

2. My new book on GOLF will give the reader valuable playing tips and insider information I've gained through my years of lessons, struggles and experiments. Here are just a few of the chapter titles: Chapter 1 - How to Properly Line Up Your Fourth Putt.. Chapter 4 - How to Get More Distance off the Shank.

3. Redox and Combustion: At the conclusion of our time together, you should be able to: 1.Identify a basic combustion reaction 2.Show the change in oxidation numbers for a combustion reaction

4. 5. Combustion Reactions Combustion reactions occur when a hydrocarbon reacts with oxygen gas. Combustion reactions occur when a hydrocarbon reacts with oxygen gas. This is also called burning!!! In order to burn something you need the 3 things in the “fire triangle”: This is also called burning!!! In order to burn something you need the 3 things in the “fire triangle”: 1) A Fuel (hydrocarbon) 2) Oxygen to burn it with 3) Something to ignite the reaction (spark) 1) A Fuel (hydrocarbon) 2) Oxygen to burn it with 3) Something to ignite the reaction (spark)

5. Combustion Reactions In general: C x H y + O 2  CO 2 + H 2 O In general: C x H y + O 2  CO 2 + H 2 O Products in combustion are ALWAYS carbon dioxide and water. (although incomplete burning does cause some by- products like carbon monoxide) Products in combustion are ALWAYS carbon dioxide and water. (although incomplete burning does cause some by- products like carbon monoxide) Combustion is used to heat homes and run automobiles (octane, as in gasoline, is C 8 H 18 ) Combustion is used to heat homes and run automobiles (octane, as in gasoline, is C 8 H 18 )

6. What Do You Get When You Cross a Snowman With a Vampire? Frostbite. Frostbite.

7. Combustion Reactions Combustion Reactions Edgar Allen Poe’s drooping eyes and mouth are potential signs of CO poisoning.

8. Combustion of Pentane: Predict the products and balance the reaction: Predict the products and balance the reaction: C 5 H 12 + O 2  CO 2 + H 2 O 568

9. Predict the products and balance the reaction: Predict the products and balance the reaction: C 3 H 7 OH + O 2  CO 2 + H 2 O Combustion of Propanol 2689

10. Combustion of Methane and Redox CH 4 + O 2  CO 2 + H 2 O CH 4 + O 2  CO 2 + H 2 O Show the change in oxidation numbers: Show the change in oxidation numbers: C -4  C +4 C -4  C +4 Each carbon loses 8 electrons – oxidation, reducing agent O  O 2- O  O 2- Each oxygen gains 2 electrons – reduction, oxidizing agent 122

11. This Does Seem a Little Weird???

12. Redox and Combustion: Let’s see if you can: 1.Identify a basic combustion reaction 2.Show the change in oxidation numbers for a combustion reaction

13. Practice Predict the products and balance the reaction of hexene burning in air: C 6 H 12 + O 2  C 6 H 12 + O 2  CO 2 + H 2 O Show the change in oxidation numbers: Show the change in oxidation numbers: C -2  C +4 C -2  C +4 Each carbon loses 6 electrons – oxidation, reducing agent O  O 2- O  O 2- Each oxygen gains 2 electrons – reduction, oxidizing agent 6 69
