Reaction that involves a substance rapidly combining with oxygen, usually accompanied by a flame.
All combustion reactions require ignition. Ignition is often in the form of friction (e.g. striking a match) or electrical energy (e.g. an electrical spark or lightning strike).
Combustion also needs a type of fuel to react with oxygen.
Combustion is a fast reaction that releases energy in the form of heat, light and sound.
- Propane (LPG)
magnesium + oxygen → magnesium oxide + energy (heat, light and sound)
Very fast combustions result into explosions.
