Transcript of Combustion Reactions

Combustion Reactions
What variety of substances can be combined to result in the reaction?
Experiment: Gummy Bear Sacrifice
Patterns for predicting Combustion Reactions
We can predict its reaction and product by the elements involved.
For instance, 2C8H18 + 25O2 ---> 18CO2 + 16H2O, as you can see, the element Oxygen, Hydrogen, and Carbon are present on the reactant and the product will always be carbon dioxide and water.
What are the features of a combustion reaction?
First of all, the features of a combustion reaction are: heat and light and chemical change especially oxidation.
Also Dihydrogen Oxide and Carbon Dioxide are released in the end product.
Equation: C12H22O11(s) + 12O2(g) ---> 12CO2(g) + 11H2O(l)
Sample Equations of Combustion Reactions
CH4(g) + 2 O2(g) ---> CO2(g) + 2 H2O(g)
In this reaction, Methane (CH4) reacts with Oxygen (2O2) to form carbon dioxide (CO2) and water (2 H20)
Substances that can be combined are hydrocarbons and oxygen. The products of combustion reaction are Carbon Dioxide (CO2) and Water (H2O).
What are Hydrocarbons?
Hydrocarbons are organic compounds made up of entirely hydrogen and carbon.
Some examples of hydrocarbons are: Methane, Ethane, Propane, Butane, Pentane, Hexane, Heptane, and Octane.
What are some everyday examples of combustion reaction?
Some everyday examples of combustion
reactions are: burning of candles, using a lighter,
using propane for grills, or even gas for vehicles.
How do combustion reactions affect everyday life?
Many combustion reactions help us with our daily needs or the energy we must have.
For example many of the common fuels we use being: natural gas, propane, kerosene, gasoline, etc, are composed of hydrocarbons. So many of the engine systems or furnaces we have rely on hydrocarbons because these reactions release heat which can directly be used to heat up a building or grill or be used as energy to power up vehicles.
Experiment: Whoosh Bottle
2 (CH3)2 2CHOH(g) + 2 O2(g)---> 6 CO2 + 8H2O(g)
Experiment: Methane Bubbles
Equation: CH4(g)+2O2(g)--->CO2(g)+2H2O(l)
A different form of combustion reaction that is important to our body is the burning of glucose.
