Chapter 7 Section 10 Combustion Reactions By: Kristina S, Nick S, Chris T

What is a Combustion Reaction? A combustion reaction occurs when an element or a compound reacts with Oxygen, often producing energy in the form of heat and light

What is needed for a combustion reaction Hydrogen Carbon Oxygen A hydrocarbon such as methane, propane, butane, and octane

How to create a combustion reaction equation (unbalanced) Butane - C₄H₁₀ C₄H₈ + O₂ CO₂ + H₂O

Make the skeleton Equation Make an equation with Octane. (C₈H₁₈) C₈H₁₈ + O₂ CO₂ + H₂O C₈H₁₈ + 2O CO₂ + H₂O C₈H₁₈ + HO₂ CO₂ + H₂O C₈H₁₈ + CO₂ CO₂ + H₂O

How to balance a combustion reaction equation To balance a combustion reaction equation there has to be equal number of atoms for each element on both sides. To do this you must place coefficients in front of each compound making all of the same element’s atoms equal.

Balance the equation Glucose - C₆H₁₂O₆ _________ + O₂ CO₂ + H₂O

Facts Combustion reactions involve oxidation and reduction. Before a substance will burn, it must be heated to its ignition point, or kindling temperature. Combustion Reactions mostly have to do with burning and heating.

Write the balanced equation for the complete combustion of ethane. Homework Question Write the balanced equation for the complete combustion of ethane.
