Doris Kra 05/03/2019 Chemistry Miss. Block What is a combustion reaction A combustion reaction is when a hydrocarbon reacts with oxygen and creates carbon dioxide and water. The formula for a combustion reaction is Hydrocarbon + Oxygen→ Carbon dioxide + Water. A combustion reaction is a common reaction in chemistry it can also be referred to as burning. A combustion reaction is a exothermic reaction because it is releasing heat or energy. (b) Some examples of a Combustion reaction are: Combustion reaction of Methane CH₄(g) + 2 O₂(g)→ CO₂(g) + 2 H₂O(g) Combustion reaction of Propane 2 C₃H₈(g) + 7 O₂(g) → 6 CO₂ (g) + 8 H₂O(g) Combustion reaction of Ethane
Reactions Complete Versus Incomplete Combustion So there is something we call a complete combustion and the other a dirty combustion. Fuel such as petrol or methane, etc can undergo complete or incomplete combustion. When methane completes a complete combustion it produces carbon dioxide and water. When methane goes through an incomplete under a limited amount of air it produces carbon monoxide and water or carbon or water. What is Combustion? There are many types of combustion. But I believe the most known one is the combustion with methane which is the one I put above. Combustion can also be called burning. Combustion is an exothermic reaction which means it gives out heat. Reaction above is a combustion reaction. This the formula CH4 + 2O4 -----> CO2+ 2H2O * In order to know if a formula is perfectly balanced you need to know that there are the exact number of molecules on the rea
