1 Chapter 7 Section 10 Combustion Reactions By: Kristina S, Nick S, Chris T
2 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
3 What is needed for a combustion reaction HydrogenCarbonOxygenA hydrocarbon such as methane, propane, butane, and octane
4 How to create a combustion reaction equation (unbalanced) Butane - C₄H₁₀C₄H₈ + O₂ CO₂ + H₂O
5 Make the skeleton Equation Make an equation with Octane. (C₈H₁₈)C₈H₁₈ + O₂ CO₂ + H₂OC₈H₁₈ + 2O CO₂ + H₂OC₈H₁₈ + HO₂ CO₂ + H₂OC₈H₁₈ + CO₂ CO₂ + H₂O
6 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.
8 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.
9 Write the balanced equation for the complete combustion of ethane. Homework QuestionWrite the balanced equation for the complete combustion of ethane.
