How is oxygen used in the process of burning?

The term for this is Rapid Thermal Oxidation. The process of burning is actually a chemical reaction called oxidation, where oxygen (oxidizer) reacts with the carbon (fuel) producing water, CO2 and heat. A much slower version of this can be observed whenever you see a piece of steel or iron rusting.

Why is it dangerous to use oxygen in a fire?

The extra oxygen makes this risk especially dangerous since the combination of spark, fuel, and oxygen could lead to a serious fire or explosion. Oxygen does not burn. It is not flammable, but it is an oxidizer. Oxygen feeds fire, so it’s dangerous to use around something that is burning because it will help the fire burn much more quickly.

What makes a fire burn and what makes it burn?

In other words, when something burns, there’s no un-burning it. Fire also is a glowing reminder of the oxygen that pervades our world. Any flame requires three ingredients: oxygen, fuel and heat. Lacking even one, a fire won’t burn.

What happens when hydrogen bonds with oxygen in a fire?

When hydrogen bonds with oxygen, it produces water vapor — even as the wood burns. Fires burn only when all that atomic shuffling releases enough energy to keep the oxidation going in a sustained chain reaction. More atoms released from the fuel combine with nearby oxygen.

Why does a fire need oxygen to burn?

Fire needs oxygen because when we burn a material we actually induce a reaction of the material with oxygen. The energy that is released during this by this chemical reaction produces what we call fire.

Why do you need an oxidizer for burning?

“Burning” is a rapid exothermic oxidation reaction, so you need some sort of oxidizer. Gaseous oxygen serves quite well, as well as oxygen bound up in various solids like nitrates (e.g. potassium nitrate in gunpowder).

Why is oxygen such a reactive chemical in burning?

So if we have carbon and we oxidize it to form carbon dioxide, the reaction of carbon with oxygen will release a lot of energy in the form of heat. Therefore, oxygen is necessary for burning because that is how we define burning. A different way to think about the question might be, why is oxygen such a reactive chemical?

Is the absence of oxygen necessary for burning?

No oxygen is not required for burning it can be done in the absence of oxygen in vacuum also . But combustion necessarily needs oxygen . Combustion does not always give rise to fire.it produces water CO2 and energy in any form. Eg.glucose metabolism. While burning gives fire but the by products are not specific.
