Oxygen (O2)
Oxygen is essential to support any combustion; combustion is a chemical process of oxidation.
It does not support combustion...
The chemicals caused by combustion are dangerous.
Chlorine gas supports the vigorous combustion of many elements to form their chlorides. For example, Sulphur and Phosphorus burn in the gas.
The materials of the candle as waxes, paraffin.
Hydrogen is a fuel for combustion, but cannot support it in the manner than oxygen can.
combustion
No. The sun is about 1% oxygen but it does not carry out combustion. It is instead powered by nuclear fusion.
Yes: oxygen and fuel compound react together.
it depends. complete combustion of butane will produce carbon dioxide and water, but incomplete combustion (not enough oxygen) will produce carbon monoxide and carbon (soot). most commonly there will be a mixture of these four chemicals produced
The combustion engine releases a lot of chemicals and smoke into the air. This raises nitrogen in the atmosphere and pollutes the air.
Combustion generally requires at least 16% oxygen in the air for sustained burning. This is known as the oxygen concentration level necessary to support combustion. If the oxygen level falls below this threshold, combustion may not occur or may be incomplete.
