GCSE Chemistry - Alkanes - Properties & Combustion (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. Properties of alkanes and how they change with carbon chain length. The trend in boiling points. State at room temperature (gas, liquid, solid). Volatility, viscosity, and flammability. 2. The complete combustion of alkanes. The reactants (hydrocarbon and oxygen) and products (carbon dioxide and water). Explanation of combustion as an exothermic oxidation reaction. 3. How to write and balance chemical equations for complete combustion. A step-by-step worked example for the combustion of propane. A step-by-step worked example for the combustion of nonane. ** CHAPTERS ** 0:00 Introduction to Alkanes 0:41 Boiling Point and State at Room Temperature 1:20 Volatility, Viscosity and Flammability 1:51 Complete Combustion of Hydrocarbons 2:46 How to Balance the Combustion Equation for Propane 3:52 How to Balance the Combustion Equation for Nonane 4:46 Summary of Alkane Properties and Combustion ** PLAYLISTS **    • KS3 Biology      • KS3 Chemistry      • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #GCSE #Chemistry #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE
