What is a Combustion Reaction? A combustion reaction is a reaction in which a substance combines with oxygen, releasing a large amount of energy in the form of light and heat. Combustion reactions commonly involve hydrocarbons. Hydrocarbons are compounds containing carbon and hydrogen. Types of Combustion Reactions There are two types of combustion reactions involving hydrocarbons. The first type of combustion reaction is called an incomplete combustion reaction are C and/or CO and H 2 O . Here is an example of an incomplete combustion 2C 3 H 8 + 7O 2 → 6CO + 8H 2 O The second type of combustion reaction is called a complete combustion reaction. The products of a CO 2 and H 2 O . Here is an example of a complete combustion reaction. CH 4 + 2O 2 → CO 2 + 2H 2 O When you are predicting the products of a combustion reaction, you should assume that the reaction is a complete combustion reaction. Therefore the general equation for a combustion The values of x and y can be the same or different. For example: C Write balanced equations for the complete combustion of the following substances: 1. 2 C 2 H 6 + 7O 2 → 4CO 2 + 2. 2 C 3 H 6 + 9O 2 → 6CO 2 + 6H 3. C 5 H 12 + 8O 2 → 5CO 2 + 6H Oxidation-Reduction (Redox) Reactions What are redox reactions? Oxidation-reduction (redox) reactions are the chemical changes that occur when electrons are transferred between reactions. Examples include the burning of gasoline and the rusting of a nail.
