What else can I help you with?
Why might you note that blowing or fanning hot charcoal briquettes cause them to glow more brightly?
Increase air flow = increased oxygen flow = increase in burn temperature and rate.
What is the equation for the test for pure oxygen?
The test for pure oxygen can be conducted using a glowing splint. When a glowing splint is introduced into a sample of oxygen, it will reignite and burn brightly if the gas is indeed pure oxygen. This reaction occurs because oxygen supports combustion more effectively than air. Therefore, the presence of pure oxygen can be confirmed by the splint's reaction.
Which elements are more reactive with oxygen group 1 or group 11?
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.
Does oxygen make things burn brighter?
Oxygen is what makes things burn at all. The more oxygen there is, the brighter it can burn.
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 gas would make a burning splint burn more brightly?
The gas is Oxygen. It burns brighter because Oxygen supports combustion (aka helps other objects to burn).
What gas is present if a lit match flares up brightly?
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.
Why might you note that blowing or fanning hot charcoal briquettes cause them to glow more brightly?
Increase air flow = increased oxygen flow = increase in burn temperature and rate.
why fire fighters use pressurized air but not oxygen in the breathing apparatus?
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.

Why does magnesium burn more in oxygen that in air?
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).
Which elements are more reactive with oxygen group 1 or group 11?
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.
What observation would show you that a substance is burning in pure oxygen?
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.
If you put a match in pure oxygen will the oxygen burn?
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.
Does oxygen make things burn brighter?
Oxygen is what makes things burn at all. The more oxygen there is, the brighter it can burn.
Do Alkali earth metals react with oxygen?
Alkali earth metals react with oxygen to form basic oxides.
How does oxygen affect how long a candle burns for?
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.
