What color does sulfur turn a flame with oxygen?
Sulfur burns in oxygen with a blue flame.
When fossil fuels burn do they produce oxygen?
No, the flame needs the oxygen to burn. Without oxygen, the flame would go out.
What color is a gas flame that is starved of oxygen?
This is a red flame.
What causes a burner flame to be smoky and to separate from the tip of the burner?
If there is not a sufficient supply of oxygen, the flame will be smoky from excess of carbon.
Why is a blue flame noisier than the yellow flame?
A blue flame is louder than a yellow flame because there is more oxygen (air) flow present than with a yellow flame. The yellow flame indicates a lack of oxygen and incomplete combustion of the methane gas.
Which flame is used for welding brass?
natural flame using a mixture of one-to-one ratio of acetylene and oxygen.
What gas bursts into flame when it reaches oxygen?
air will burst into flame in pure oxygen

No, the flame needs the oxygen to burn. Without oxygen, the flame would go out.
What color is a gas flame that is starved of oxygen?
This is a red flame.
When is the flame extinguished?
This occurs only when the flame is robbed of oxygen.
Why does the flame of a candle die when you cut off air supply?
Oxygen is needed for burning. If there is no oxygen flame dies.
What causes a burner flame to be smoky and to separate from the tip of the burner?
If there is not a sufficient supply of oxygen, the flame will be smoky from excess of carbon.
Why is a blue flame louder then a yellow flame?
because a flame needs oxygen to burn so when you allow the oxygen to flow it will suddenly burst up with oxygen creating a sound since it is now burning properly.
Why is a blue flame noisier than the yellow flame?
A blue flame is louder than a yellow flame because there is more oxygen (air) flow present than with a yellow flame. The yellow flame indicates a lack of oxygen and incomplete combustion of the methane gas.
Why does a flame not get extinguished when a wire gauze was placed on top of it in a candle observation chemistry lab?
A flame is not extinguished when a wire gauze is placed on top of it because the flame is still exposed to oxygen. The gauze has holes, through which oxygen can flow. Additionally, oxygen can reach the flame from under the gauze. Consequently, the flame is not extinguished.
How does fire go out if its covered by a jar?
Fire requires oxygen to burn. No oxygen = no flame. When you put a flame in a jar it lives off the oxygen inside the jar for a while. Once you put a lid on the jar, eventually the jar will run out of oxygen and the flame will burn out.
