there isn't an actual chemical to start fire. all you need is an ignition source, oxygen, and a fuel source (such as wood)
fire
A fire (burning, combustion) is a chemical process.
because its a chemical reaction
All opals are hydrated amorphous forms of silica: SiO2.nH2O.
its chemical because if a wood catches on fire it turns to ashes and thats chemicl cause you cant make it change back to a log
fire
a fire with a chemical in it
It is not a chemical change, unless you heat it sufficiently to make it catch fire.
Fire + CuZn Battery
Fire is a chemical reaction. A forest fire is a disaster consisting of chemical reactions.
Candles make chemical energy because the fire makes chemical energy!
A fire is a chemical change due to the irreversible changes that happen.
Fire is a chemical reaction (oxydation).
It is not a chemical change, unless you heat it sufficiently to make it catch fire.
Heat source Oxygen Fuel or a combustible and a chemical reaction
Fire is not a physical or chemical property. Fire is not a property. Fire is a chemical reaction where oxygen combines with some or all of the chemical components of the fuel, emitting light and heat.
A fire (burning, combustion) is a chemical process.
