Combustion reaction definition and everyday life examples

📚 Quick Study Guide

• 🔥 Definition: Combustion is a chemical process involving rapid reaction between a substance with an oxidant, usually oxygen, to produce heat and light.
• 🌡️ Key Components: Requires a fuel (the substance being burned), an oxidant (usually oxygen), and an ignition source (heat).
• 💧 Common Products: Typically produces carbon dioxide ($CO_2$) and water ($H_2O$). Incomplete combustion can also produce carbon monoxide ($CO$).
• ⚖️ Balancing Equations: Combustion reactions must be balanced to ensure the number of atoms of each element is the same on both sides of the equation.
• 🌍 Everyday Examples: Include burning wood, propane in a grill, and the combustion of fuel in an engine.
• 💡 Incomplete Combustion: Occurs when there's insufficient oxygen, leading to the production of carbon monoxide, a toxic gas.
• 📝 General Form: Fuel + $O_2$ $\rightarrow$ $CO_2$ + $H_2O$ (+ Heat and Light)
