1. Explaining a Combustion Reaction

2. What is Combustion Reaction?

3. What are some real-life examples of combustion reactions?  When people are cooking on a gas stove or a candle burning.  Burning wood to make a fire.  Burning coal to make electricity  Burning gasoline in a car to make the car move forward.

4. How are combustion reactions used in our daily lives?  Transportation (almost all motorized vehicles in North America except electric cars)  Burning trash to get rid of garbage (mostly in Europe and Asia)  Electricity- burning of coal  All tools…like lawnmower, leaf blower…  Industry…to make all goods and products

5. How could you describe a combustion reaction to someone who didn't have a very good background in chemistry?  Is a reaction in which oxygen reacts with an organic compound (generally a hydrocarbon) to produce energy in the form of heat and light.  When organic molecules combust the reaction products are carbon dioxide and water.

6. 2 Types of Chemical Reactions!!!  Complete  Clean combustion with a hydrocarbon produces carbon dioxide and water  Incomplete  Dirty combustion with a hydrocarbon produces carbon or carbon monoxide also carbon dioxide.

7. Incomplete Combustion Facts and Concerns  Other products formed are C (s), soot (molecules that clump together and are mostly made of carbon), CO (g), unburned fuel  Flame is more yellow (1200 o C) than blue (1400 o C)  Occurs in less than ideal conditions like lack of oxygen  Furnace for example might be malfunctioning  Soot particles are an inhalation hazard. They can lead to various problems like asthma, lung cancer..  Carbon monoxide is colorless and odorless and is called the silent killer  On average 7 Ontarians are killed every year from accidental carbon monoxide poisoning…Ontario now requires by law that every household has a carbon monoxide detector  Loss of fuel…inefficiency and waste
