There is what is known as a "fire/combustion" triangle, which has the three components necessary for fire: oxygen, fuel, heat
there isn't an actual chemical to start fire. all you need is an ignition source, oxygen, and a fuel source (such as wood)
The three factors needed for a fire are heat, fuel and oxygen. Note that these are not elements in the chemical sense. (Oxygen is, but most fuels are compounds or mixtures, and heat is energy, not matter.)
The candle will cease to burn because oxygen is needed for burning. This is why one of the ways to extinguish a flame is to remove its source of oxygen, as described in the fire triangle.
You're looking at a fire triangle. Fire refers to an ignition source, a spark, or similar which will cause the combustion reaction to begin. Fuel refers to the object which will be burned in the reaction. Oxygen is, exactly what it says, Oxygen. Which is required for combustion reactions.
the air
A source of heat, a source of fuel, and oxygen.
That the supply of oxygen for the fire
Fire needs the oxygen in the air. Any other source of oxygen would also sustain fire.
The main features of a fire include heat generation, light emission, and the rapid oxidation of a material in a combustion process. Fires also typically produce smoke and gases as byproducts.
To create a fire you need a fuel source of some kind, oxygen (O2), and a heat source.
Fuel, Oxygen and a heat source. Fuel, Oxygen and heat are everywhere why is the whole earth not on fire? because it is not Heat but a source of ignition that is needed.
