Oxygen is required to have a flame. If there is too little oxygen available, the flame will go out.
Natural atmospheric levels of carbon dioxide have no effect on the flame. If the CO2 concentration is high enough, it can extinguish the flame by lowering the amount available oxygen e.g. covering a candle with a jar.

∙ 13y agoCarbon Dioxide is a heavy gas, commonly stored compressed in a cylinder for use as a fire extinguisher. The gas does not react with most substances and so does not support combustion on anything less reactive than carbon.
When released from high pressure containment, the gas rapidly expands. Since the expansion requires heat, the gas takes the heat from its surroundings. When directed at a fire then the first effect is to remove heat from the fire. Secondly, the gas displaces the air involved in the burning process and thus removes the oxygen necessary to sustain the combustion. The net effect is that carbon dioxide tends to put out fire in the area that it is used.
There are other effects too. The force of the blast of carbon dioxide can spread flammable materials if used without caution or proper training, and as the carbon dioxide disperses with time, materials previously burning may re-ignite. Carbon dioxide is of limited effectiveness for extinguishing fire in unconstrained locations.

What element puts out a flame?
Carbon dioxide Carbon dioxide remove oxygen by any means
Does carbon monoxide burn?
Yes, carbon monoxide burns with a blue flame, producing carbon dioxide.
Which gas makes burning magnesium go out?
Nitrogen would extinguish the flame. Unlike most burning fuels, magnesium will continue to burn in carbon dioxide because its flame is hot enough to decompose carbon dioxide to carbon and oxygen.
Hydrogen and carbon dioxide cannot be seen how could you use a wooden splint and a flame to identify each of these gases?
You can identify hydrogen and carbon dioxide by lighting a wooden splint and putting it near the gasses. Since hydrogen is flammable, the flame will get bigger. Since carbon dioxide does not burn, it may get smaller or go out.
If you burn a candle will there be carbon dioxide?
The flame will go out, because carbon dioxide removes the oxygen from the area surrounding the flame. Fire requires oxygen to burn, much like humans need oxygen to breath, and similar to carbon dioxide does to humans, the flame will lose its oxygen and go out.
What element puts out a flame?
Carbon dioxide Carbon dioxide remove oxygen by any means
What gas puts out a flame?
CO2(carbon Dioxide)
What happens when you put a flame into carbon dioxide fumes?
The flame will go out as it is deprived of oxygen.
What chemical is given off in a burning flame?
The principal components are carbon dioxide, water, carbon monoxide, sulfur dioxide, soot.
What gas comes off a burning flame?
Carbon dioxide and water vapor come from a flame.
Does carbon monoxide burn?
Yes, carbon monoxide burns with a blue flame, producing carbon dioxide.
Which gas is needed to put out a flame?
Co2 (carbon dioxide) x
What of these will show that a gas is carbon dioxide?
to see if a gas given off is carbon dioxide you can trap gas in a test tube light a splint and place in tube if flame goes out then it is Carbon Dioxide
Which gas makes burning magnesium go out?
Nitrogen would extinguish the flame. Unlike most burning fuels, magnesium will continue to burn in carbon dioxide because its flame is hot enough to decompose carbon dioxide to carbon and oxygen.
Does carbon dioxide cause a small explosion when exposed to flame?
No. In fact, a pure CO2 atmosphere will snuff out a flame.
