What else can I help you with?
What is the color of the flame when hydrogen is burn?
It burns a distinct bright orange/red color which is unique to hydrogen alone.
Does pure hydrogen burn in the absence of air?
No hydrogen will not burn in the absence of air unless another oxidizer is present.
When you burn hydrogen and oxygen what molecule is created?
When you burn hydrogen and oxygen, the molecules combine to form water (H2O).
What colour does hydrogen burn?
Hydrogen burns with a pale blue flame.
Can water burn, and if so, under what conditions does water burn?
Water itself does not burn, as it is a compound made of hydrogen and oxygen. However, hydrogen, which is a component of water, can burn under specific conditions. Hydrogen can burn in the presence of oxygen and an ignition source, such as a spark or flame. This reaction produces water vapor and heat.
Can a red dwarf burn hydrogen?
A red dwarf fuses hydrogen into helium, just like any star, albeit at a very conservative rate.
Are main sequence stars older than red giants?
No, red giants are generally older than main sequence stars, as red giants have no hydrogen left for fuel, and burn helium instead. where as Main Sequence stars burn hydrogen for fuel.
What Stars burn hydrogen?
All stars 'burn' hydrogen
What does a red dwarf sun burn?
Like all main sequence stars, a red dwarf is powered by the fusion of hydrogen into helium.
What is the color of the flame when hydrogen is burn?
It burns a distinct bright orange/red color which is unique to hydrogen alone.
Does pure hydrogen burn in the absence of air?
No hydrogen will not burn in the absence of air unless another oxidizer is present.
How is helium and hydrogen used on a large scale?
helium does not burn, hydrogen will burn in air
What is a star called that has exausted its supply of oxygen?
Stars are powered by fusing hydrogen, not oxygen. A star that has exhausted the hydrogen in its core may continue to burn as a red giant.
What does it take to make hydrogen burn?
Hydrogen gas is highly flammable; you can make it burn with the slightest spark.
Can you get hydrogen back if you burn it?
Yes. When you burn hydrogen the product is water. If you pass an electric current through that water you can split it back into hydrogen and oxygen.
How do you burn sea water?
You don't. Sea water is the combustion byproduct of hydrogen. That is, water is water you get when you burn hydrogen.
Do different types of stars burn different fuel?
Yes, young stars burn Hydrogen and produce Helium. As they age, they often turn into red giants, and at that time they burn the Helium, making Oxygen and Carbon. Very large stars can even burn the Oxygen and Carbon, making even heaver elements, such as Iron.
