Why carbon-dioxide supports the combustion of magnesium?
Carbon dioxide does not support the combustion of magnesium; it acts as a fire suppressant by displacing oxygen. Combustion requires oxygen, so the presence of carbon dioxide can inhibit the reaction by reducing the concentration of oxygen available for combustion.
Difference between helium gas and oxygen gas?
Helium is an inert gas, colorless, odorless, and tasteless. It is lighter than air and does not support combustion. Oxygen, on the other hand, is a reactive gas that is essential for combustion and respiration. It is odorless, colorless, and tasteless, and supports life due to its role in cellular respiration.
Is more oxygen used in an incomplete combustion than a complete combustion?
Yes, more oxygen is used in incomplete combustion compared to complete combustion because incomplete combustion results in the partial burning of the fuel, leading to the formation of more byproducts like carbon monoxide and soot. This requires additional oxygen to combine with these byproducts, using up more oxygen overall.
Why do iron and magnisium burn more in oxygen than in air?
Iron and magnesium burn in air under the right circumstances becasue they combine rapidly with oxygen. (Fire is just the rapid combination of oxygen or another oxidizer, wiht a fuel.) Oxygen is only about 20% of air. If you provide pure, 100%, oxygen under the same circumstances, there is more oxygen to combine with the iron or magnesium, so they can burn faster.
What material provides the oxygen necessary to the combustion of the charcoal?
Oxidizers provide the oxygen neccesary for the combustion of charcoal. Oxidizers are common in the use of propellants, especially for rockets where there is an environment that has zero atomsphere present. An oxidizer is a type of chemical which a fuel requires to burn. Most types of burning on Earth use oxygen, which is prevalent in the atmosphere. However in space there is no atmosphere to provide oxygen or other oxidizers so rockets need to carry up their own oxidizers. Usually, they are carried in a different tank than the fuel and released in the proper proportion with the fuel when the rocket is fired.

Why does complete combustion release more energy than incomplete combustion?
Complete combustion occurs when a fuel reacts with oxygen to form carbon dioxide and water, releasing more energy because all the fuel is efficiently converted into these products. In incomplete combustion, not all the fuel reacts to form carbon dioxide and water, leading to the release of less energy as other byproducts such as carbon monoxide or soot are formed.

Is there anything that will burn without oxygen?
Titanium burns in nitrogen as well as oxygen. You might get some argument that combustion mean "in oxygen" but I think it is fair to say that lots of things "burn" in something other than oxygen. They undergo chemical reactions while giving off light and heat.Combustion is a process in which some is oxidized in an exothermic reaction. Things can be oxidized by other chemicals than oxygen, such as Cl2 or F2, and that would be considered combustion.Pyrolysis is a thermochemical reaction in which organic matter undergoes decompostion(or combustion in another sense) in the absense of oxygen.This is a clear example of combustion without oxygen.See the Web Links to the left for more information.
WHAT WILL HAPPEN IF THE ELECTRIC BULB S FILLED WITH OXYGEN GAS?
If an electric bulb is filled with oxygen gas, the filament inside the bulb would burn brighter and hotter than if it were filled with normal air. However, this can be dangerous as oxygen supports combustion and can increase the risk of a fire hazard if the filament overheats. It is not recommended to fill electric bulbs with pure oxygen gas.
What atoms should be balanced last when balancing hydrocarbon combustion reaction?
The oxygen atoms
Does carbon burn in a vacuum?
In normal usage, 'burning' means oxygen combustion, so without a source of oxygen carbon cannot burn. Rockets get around this problem by carrying supplies of oxygen with them (although rockets usually burn hydrogen rather than carbon compounds). Further, given sufficient temperatures, carbon compounds may react chemically with other available substances, which may be considered a kind of burning
Does liquid oxygen burn or oxidize?
It burns, e.g. rocket fuel; it does not oxidize as it only appears in O2 rather than O as it is not stable enough to exist on its own. So the one oxygen atom has its octet rule fulfilled by the second, while the second has a half filled valence electron shell making it stable.
Can hydrogen support combustion?
Hydrogen is a fuel for combustion, but cannot support it in the manner than oxygen can.
What is the rate or speed of combustion in a high concentration of oxygen pure oxygen compared to combustion of a low concentration of oxygen air?
Combustion in a high concentration of pure oxygen is significantly faster than combustion in low concentration air because there are more oxygen molecules available to react with the fuel. The higher oxygen concentration allows for more efficient combustion and a faster reaction rate. However, it can also increase the risk of fire hazards due to the greater availability of oxygen.
Why do you burn food in oxygen and not in air?
Burning food in pure oxygen (rather than air) accelerates the combustion process because oxygen is the key component needed for fire. Air is a blend of gases, with only about 21% oxygen, while pure oxygen provides a more efficient environment for combustion to occur. This allows for faster and more intense burning of the food.
