Either it has been extinguished, or it has burned down. Extinguishing a candle can be done by snuffing the candle, thus depriving the flame of oxygen, or by blowing it out. I am guessing you're more interested in the latter, so here goes, to the best of my ability. A flame is a byproduct of a chemical reaction, usually an oxidation process. Some element from the fuel, generally carbon, is combining with natural oxygen in the air. the flame is the heat and light energy given off by this reaction. As with all reactions, when one element runs out, the reaction ends. So in the case of snuffing the candle, the oxygen runs out, or in the case of a candle burning down, the fuel runs out, so there is nothing to combine with the oxygen, ending the reaction. Unless of course something else catches fire. Then you've got a bigger problem.
The fuel of the candle is the wax. The heat from the flame melts the wax which is drawn up the wick by capilary action and burns to feed the flame. The flame travels down the wick as the candle melts revealing more wick.
Interestingly, a non-flammable wick would work just as well (the Romans used asbestos for lantern wicks) but the non-flammable wick would droop as the candle burned down and channel the molten wax away from the flame, or potentially spread the flame wider creating an uncontrolled burn. Which is why flammable wicks are used which burn away as the flame travels down.
The activation energy for the combustion reaction that takes place when the candle burns is too great for the reaction to begin at room temperature without the input of energy (such as by lighting it with a match). However, once the reaction has been started, it produces enough energy to sustain itself. This is why the candle continues to burn.
The activation energy given by the burning match causes the candle to burn. This activation energy is supplied by the thermal energy, which is released as the match burns.
Because you can't do it because the wood on the match turns to charcoal, which is very fragile.
Because the wick has reached the temperature of combustion and is burning on its own.
When a lit match is touched to the wick of a candle, the candle begins to burn. When the match is removed, the candle continues to burn.
it depends on the size of the candle. no it really doesnt! so be quitte
the white candle will burn faster because it doesnt have the extra weight of coloured die
actually the color does not effect how fast the candle burn, i got confused of " Does candle's color effect how candle's burn?"but i think the color does not effect how candle burns. But some people will think that the white or yello candle will burn slower because color will obsorb the heat more. Hope i have answered your question.
Yes, thicker candles have more wax to burn and therefor take longer to burn out.
I'll burn your head. That is what the match say to candle.

no unless you are in a submarine.

unscented candles burn faster because its made with a type of wax that doesnt have fuuels and the less the fuels the faster it burns
It shouldn't unless something added to it makes it burn faster. Even a non-scented candle really has a smell, the smell of melting wax.
There is no way to tell unless you know the size of the candle, the exact makeup and proportions, the environment surrounding the candle etc.
Burning a candle is not spontaneous combustion. That is when something ignites with no outside heat source. If a candle burst into flame with no match or lighter, THAT would be spontaneous combustion.
a flame will continue to burn until all the oxygen is gone. then it will go out.
the white candle will burn faster because it doesnt have the extra weight of coloured die
no it will not it needs carbon dioxide to burn, without it theres no way the candle will be able to burn
a candle takes longer to burn but it smells nicer, especially if it is a scented candle
