the general formula for combustion is someting like this:
organic (carbon/hydrogen based substance)+ oxygen goes to carbon dioxide+ water + ash
pure oxygen is a very important component of this reaction, but normal air is less than a quarter oxygen, so the effect is diluted
Increase air flow = increased oxygen flow = increase in burn temperature and rate.
Elements in group 1 (alkali metals) are typically more reactive with oxygen compared to group 11 (coinage metals). This is because alkali metals have a lower ionization energy and are more likely to form ionic compounds with oxygen.
Oxygen is what makes things burn at all. The more oxygen there is, the brighter it can burn.
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.
yes it does, that's why your always told to keep all doors closed when a fire is inside!
The gas is Oxygen. It burns brighter because Oxygen supports combustion (aka helps other objects to burn).
Oxygen is present in the air, which is a necessary component for a lit match to flare up brightly because it supports combustion. When a match is struck, the heat causes the sulfur in the match head to react with oxygen, producing a flame.
Increase air flow = increased oxygen flow = increase in burn temperature and rate.
Things burn much more easily in oxygen than in air. For instance, if you put a match that is just smouldering in air into a jar of oxygen it will flare up and burn brightly. Think of what might happen to a fire fighter breathing oxygen in a smouldering building! Then of course there's the basic fact that human beings are meant to breathe air, not oxygen, in the first place.
First off, it doesn't burn more, it burns quicker. This is because It's reacting with the oxygen, and in a 100% oxygen environment there's simply more oxygen to react with (the air is 21% oxygen).

No, oxygen itself does not burn. Oxygen only supports and accelerates combustion when there is a fuel source present. So, while the match may burn more intensely in pure oxygen, the oxygen itself does not burn.
That you can get burnnes and not wearing safety googleto. And oxygen cant be wasted alot because you have to pay more money for heat. That you can get burns and not wearing safety google to. And oxygen cant be wasted alot because you have to pay more money for heat.
Oxygen is what makes things burn at all. The more oxygen there is, the brighter it can burn.
Alkali earth metals react with oxygen to form basic oxides.
Oxygen is necessary for combustion to take place. When a candle burns, it reacts with oxygen in the air to produce a flame. Increasing the oxygen supply will result in a hotter and more efficient burn, causing the candle to burn more quickly. Conversely, reducing the oxygen supply will cause the flame to burn more slowly or even extinguish.
If it's a normal fire, where normal everyday materials are burning, then pure oxygen will not put it out, it will make the fire burn stronger. Burning is a chemical reaction, and oxygen is a necessary reactant for combustion.
