No. The sun is about 1% oxygen but it does not carry out combustion. It is instead powered by nuclear fusion.

How can oxygen produce combustion?
Oxygen is a required reactant in a combustion reaction - without oxygen, you do not have combustion. If you combine a hydrocarbon with oxygen and add heat, you will cause a combustion reaction that results in carbon dioxide and water being formed (provided there was complete combustion).
Why is combustion reactions an oxidation reactions?
Because combustion is a reaction with oxygen.
Is burning of oxygen combustion or decomposition?
Combustion. Any reaction that has O2 as a reactant is combustion.
How many moles of oxygen will be produced from the complete combustion of 4 moles of propane?
No moles of oxygen are produced by complete combustion of propane. Oxygen is CONSUMED, not produced. For combustion of 4 moles of propane, it will use 20 moles of oxygen.
How is combustion made?
To combustion is to undergo combustion. Combustion is a process in which a substance reacts with oxygen to give heat and light.What are always the two products of a combustion reaction?A combustion reaction is when all substances in a compound are combined with oxygen, which then produces carbon dioxide and water.
Can hydrogen support combustion?
Hydrogen is a fuel for combustion, but cannot support it in the manner than oxygen can.
What chemicals support combustion?
Oxygen (O2)
Does air support combustion?
Yes, combustion requires oxygen which is found in air.
What reactant must be present to support combustion?
Oxygen.
Why do fireworks need chemicals with therir own oxygen?
Oxygen is essential to support any combustion; combustion is a chemical process of oxidation.
Compare and contrast the relationships of oxygen and water to fire?
- Oxygen support combustion; combustion is a reaction with oxygen, an oxydation.- Hydrogen is burned with oxygen.- Water can turn off some fires.
Can you start a fire on the moon?
No. The moon has no atmosphere so there is no oxygen to support combustion.
When oxygen gas supports combustion is it called physical or chemical change?
Chemical: oxygen is one of the reactants in combustion, it does not only (passively) support it, but is taking part in it.Combustion is chemical anyhow.
Which element is required for a combustion reaction to occur?
Oxygen? no, nitrogen is an odourless and colourless diatomic gas which can be used to support combustion.
Is oxygen required in combustion?
No, oxygen is required for combustion to take place.
Is oxygen one result of combustion?
No. Oxygen is a reactant in combustion, not a product.
How is water different from the elements which made them?
Hydrogen gas and oxygen gas are gases at room temperature. Oxygen supports combustion and hydrogen is very combustible. Water is a liquid at room temperature and is not combustible and does not support combustion.
