What else can I help you with?
Is flammability of a substance is physical or chemical change?
Stating that something is flammable is stating a chemical property. But the actual burning would be a chemical change.
What colour flame would indicate ethane burning in excess oxygen?
A blue flame would indicate ethane burning in excess oxygen. Blue flames are typically associated with complete combustion and sufficient oxygen supply during the burning process.
Which observation would provide indirect evidence that the bubbles are not oxygen?
If the bubbles do not relight a glowing splint, it would suggest they are not oxygen. Oxygen is a gas that supports combustion, so if the bubbles do not allow the splint to reignite, it indicates they are not oxygen.
What gas would make a burning splint burn more brightly?
The gas is Oxygen. It burns brighter because Oxygen supports combustion (aka helps other objects to burn).
What would happen to something burning if there was only oxygen and no nitrogen?
If there was only oxygen and no nitrogen present, the burning process would be more efficient and the flames would burn brighter and hotter. Nitrogen in the air can act as a diluent, which can dampen the combustion process.
What would happen to a burning candle if you put it in the space shuttle?
It would stop burning if there was no oxygen.

What do you mean by combustion of a hydrocarbon?
Burning. Some substance, usually called the fuel, combines with oxygen, or some substance that causes oxidation, and releases heat energy as the substances are changed into some new substance(s).
Which observation would be the best evidence of oxygen cycling?
Answer this question… Moving animals

How does air help in burning?
When something burns, it needs oxygen to stay alight. There is oxygen in the air, and that lets a flame keep burning. If you were to put a glass over a flame, a candle for example, the fire would go out once it had used all of the oxygen inside and turned it into carbon dioxide.
What would happen if you tried to burn oxygen?
Nothing. Oxygen itself is not flammable. Fire is a reaction between a flammable substance and oxygen.
When you combine carbon and oxygen atoms what kind of reaction do you get?
A simple example of the combining of carbon and oxygen would be the burning of coal.
What would happen to something burning if there was only oxygen and no nitrogen?
If there was only oxygen and no nitrogen present, the burning process would be more efficient and the flames would burn brighter and hotter. Nitrogen in the air can act as a diluent, which can dampen the combustion process.
What type of chemist would describe the chemical properties of oxygen?
Since oxygen is an inorganic substance, most likely an inorganic chemist would describe the chemical properties of oxygen.
