Methanol is low molecular weight and very volatile and it is an oxygenated fuel. These factors helpm it to burn very cleanly and colorlessly.

What metal burns with a silver flame in air?

What is the gas in the gas taps and comes from under the north sea. It burns with a blue flame if there is plenty of air?
methane is in gas taps comes fro under the north sea and burns with a blue flame if there is plenty of air from gemma
Why the central blue cone in the blue flame is unburnt gas?
because no air enters it. The air burns gas.
How white flame is formed?
Yes, it is possible to have a white flame. A good example of a white flame is the flame with which a magnesium wire burns. When magnesium wire is burnt in air(oxygen), it burns with a bright white flame.
When evaporating dish is held over the flame ( air holes are closed )?
I assume the air holes are on a bunsen burner? In which case, when the air hole is closed the flame glows yellow, is less hot, and is more like the flame on a wax candle. When the air hole is opened, air is drawn in and the flame burns blue and produces a fiercer heat.
What are the two pollutants formed when methanol burns in a restricted supply of oxygen?
carbon monoxide (CO) and particulates (tiny black solid in the air)
A Bunsen burner burns with the hottest flame when its hole is fully open because this allows plenty of gas from the air to reach the flame What is this gas?
Oxygen
Is the blue flame hotter then then the yellow flame?
Yes it is. Because it gets more oxygen do therefore its hotter. It burns the air up and becomes blue.
Will a bottle rocket fly with out water?
Yes if you use compressed air inside the rocket. Or you can use agitated methanol and a flame for thrust like a whoosh rocket.
