Combustion Reactions By: Chris, Andrew, and Kacper

Combustion Reaction  A combustion reaction is when an element or a compound reacts with oxygen, often producing energy in the form of heat and light  A hydrocarbon is a compound that is usually involved in a combustion reaction. It is made of what? A. Iron, and Hydrogen B. Carbon, and Hydrogen C. Helium, and Carbon D. Hydrogen Carbonate

Product of Combustion Reaction  A combustion reaction with a hydrocarbon produces water, carbon dioxide, and heat.  A combustion reaction is commonly called burning.  Other elements and compounds can be involved in a combustion reaction however it doesn’t produce water and carbon dioxide.

How to Setup Combustion Reaction Balancing Equations  Say you have C 6 H 6, this is how you set up a hydrocarbon combustion reaction.  Tip: Balance the C and H, first then balance O C6H6C6H6 + O 2  H 2 O + CO 2

Balancing Combustion Reaction Equations CHOCHO Now it is balanced! 2C 6 H O 2  6H 2 O + 12CO 2

How a real combustion reaction works. Combustion takes place in an engine to make the pistons move.

Interactive Problems 

Homework!!  Write a balanced equation for the complete combustion of these compounds. 1. methanol, CH 3 OH 2. octane, C 8 H 18
