Combustion & Fuels
Combustion products, fuel comparisons, and pollution-linked combustion reasoning across core topics.
This route helps when you keep missing the same type of question across different topics. Use it to combine lesson notes with linked practice and tools in one place.
Notes and Hubs in This Route
- Hydrogen as a Fuel and Fuel Cells
Learn why hydrogen is a potential fuel, how a hydrogen fuel cell generates electricity directly, and how production affects its environmental impact.
- Exothermic Reactions
Exothermic reactions: definition, ΔH is negative, and how to interpret energy profile diagrams and activation energy without common traps.
- Fossil Fuels: Combustion and Emissions
Explain non-renewable fossil fuels, balance methane combustion, and connect oxygen supply and fuel composition to emissions.
- The Chemistry of Fireworks: Colour, Light, and Bangs
Fireworks are controlled combustion. Learn how oxidisers, fuels, and metal salts create colour, light, and sound.
