What happens when you cut the air supply down on a Bunsen burner?
the burner stops burning
When you rotate the collar of the Bunsen burner what is the effect of that to the air holes?
depends on the direction you turn the collar. You may cause the air holes to enlarge and let more air into the barrel of the burner. Or you could be making the holes smaller and actually cut off the air supply making the burner less effective, burning at a lower temp because of the lack of oxygen.
What kind of reaction stops when you cut off it's supply oxygen?
A combustion reaction stops when its supply of oxygen is cut off. Combustion requires oxygen to sustain the chemical process of burning, where a fuel reacts with oxygen to produce heat and light. Without oxygen, the reaction cannot continue, leading to the extinguishing of the flame. This principle is often utilized in fire suppression methods.
Does putting sand on fire cut off the supply of oxygen?
Yes, putting sand on a fire can help cut off the supply of oxygen by smothering the flames. Sand does not burn and can create a barrier between the fire and the surrounding air, helping to extinguish the flames.
A different chemical substance is formed when a piece of cloth is cut cup breaks candle burns or a piece of chalk breaks?
The candle burning is a chemical process.
Why does a candle go out when covered by a wide-mouthed jar?
When a wide-mouthed jar covers a candle, it creates a lack of oxygen inside the jar. The flame needs oxygen to burn, so when the oxygen supply is cut off, the flame extinguishes due to the lack of a crucial element for combustion.
Why cauterize flowers?
To cauterize a cut flower, immerse the fresh cut stem end in boiling water for ten seconds, or hold it over a candle flame until the ends are sealed.
What happens when the hole on a Bunsen burner is closed?
The "air-hole" of a bunsen burner allows some of the flame to escape so that the heating flame does not become too hot. A flame that is too hot can damage laboratory equipment. When the air hole is closed it is a yellow sooty flame like the fires we have at home.
What experiment could you do to prove that oxygen is needed for burnig?
simply cover a burning candle with a glass to cut off the air, then the candle will burn out
Are you supposed to cut candle wicks?
Yes, trimming the wick of a candle to about 1/4 inch before each use helps promote an even burn and prevent soot buildup. Always trim the wick when the candle is cool and not burning.
Why do candles go out when you put a beaker over it?
As we know that for an object or substance to burn, its by means of carbon. Fire is very complex and needs oxygen for it to burn so by putting a beaker over a candle you are actually cutting the consumption of oxygen by fire, which will stop the fire from burning. THAT ANSWER IS FALSE. Because the candle is under a beaker and most beakers have lips the beaker is not fully cut off from oxygen so there is still oxygen. The candle does go out because of the carbon dioxide that is in the beaker
How can I safely put out a sterno flame?
To safely put out a sterno flame, carefully cover it with a metal lid or snuffer to cut off the oxygen supply. Do not blow on the flame or attempt to extinguish it with water. Wait for the flame to completely go out before moving the sterno container.

How do you put a Bunsen burner out?
To put out a Bunsen burner, simply close the air vent to cut off the oxygen supply first, then turn off the gas supply using the valve on the burner. Never use water to extinguish a Bunsen burner as this can spread the flame.
What do you use to cut a candle in half?
To cut a candle in half, you can use a sharp knife or a sturdy utility knife. It's best to warm the candle slightly to soften the wax, which makes cutting easier. Alternatively, you can also use a saw designed for cutting soft materials if the candle is particularly thick. Always take care to cut slowly and steadily for a clean cut.
How a Bunsen burner can display both complete and incomplete combustion?
The Bunsen burner would display complete combustion by producing a "roaring" blue flame and it would display incomplete combustion when you close the air valve complete to cut off the oxygen gas supply, thus creating a yellow flame due to the burning of carbon particles (soot).
